Why constant pool with 0 entries?

I'm writing a tool that parses SWF files. Recently I see some
SWF file that has constant pool of 0 entries, yet a lot of bytes
followed. The spec does not describe what this means. For example,
using swfdump there is something like:
[00c] 141 DOACTION
( 0 bytes) action: Not
( 2 bytes) action: If 5
( 131 bytes) action: Constantpool(0 entries)
String:"ˆB" (remainder of 126
bytes:"\5\0wf_toolbar.swf\0toolbar_mc\0loadMovie\0toobar\0createEmptyMovieClip\0›\16\0Loa dToolbar\0\0\0\20\0–\9\0\8\0\7\1\0\0\0\8\1\28–\2\0\8\2R\23–\16\0\8\1\7\2\0\0\0\8\3\7\2\0\0 \0\8\4=<")
( 0 bytes) action: End
The constant pool contains 0 entries. Yet the total byte size
of this action is 131 bytes. Clearly there is meaningful
information contained in these bytes. But I just cannot find in the
spec how to parse these bytes.
Anyone can help? Thanks.

Is there any change in the constant pool entires with JDK1.4?

Hi,
Here is my simple java class,
class Base
String manuf = "MRF";
class Derived extends Base
Derived() {
manuf = "ABC";
After compiling this class with JDK 1.3 and JDK1.4, i could see the difference in constant pool entries
so please let me know more about these cahnges.
P.S. : written a java program TClass.java to browse the constant pool entries.
i.e if compiled with JDK1.3 , constant pool entries looks as follows,
E:\bugs\jdk1.4\pramila>java TClass E:\bugs\jdk1.4\pramila\Derived.class
There are 21 + 1 entries in the Constant Pool:

javac v1.4 emits by default Java 1.2 compatible .class files while all javac implementations since between 1.1.0 and 1.3.1 emit byte default Java 1.1 .class files.
Check to see what effect using the -target option in javac to get the two versions to produce Java 1.1, 1.2, or 1.3 .class files.

Palm OS: Invalid constant pool entry - What's that?

Hello,
I'm a newbie in developing application 4 my palm. (midp4palm 1.0 installed)
I started with a "hello world"... everything went fine on my tungsten t3 emulator. Label + TextField.
Then I wrote a little calculator... and now I get the following message: "Invalid constant pool entry".
I used switch(), some static final doubles and that's it.
Do you know what the problem could be... I didn't find a solution.
Thank you
mastix mc

A quick google search yielded this - hope it helps.

Summary:
* "This is usually caused by a null reference not caught by the KVM, or sometimes an instanceof sometime before."
* "I was having exactly this problem on a Palm V.
I re-downloaded the KVM from Sun's site. I am using a Mac, and I noticed
this time, after running ZipIt to unzip the files, that the types of the
files have now been correctly set. I re-installed the files, and now
everything is working fine.
My guess is that something is corrupted in your KVMClassDB.pdb file. I've
done a couple of upgrades to my Mac software and the OS upgrade, so I'd
recommend doing every possible software upgrade, then download the KVM again
and re-install it."

Alert: Invalid constant pool entry

Hi, When I install midlet application in mobile phone I got this error "Alert: Invalid constant pool entry" and says "Application Error". When I create a object of a class at that time this error occurred. In that class I have used a constant which value is 1.5. After googling so many people are saying this because of floating point value. That May be the problem. Because when I change that 1.5 value to 1 then application get installed and run. But earlier also I used to create the object of that class. At that time mobile phone did not throw any error. But why this time throw error. I did not understand what could be the problem. Please any one help me.

No. No. Both Jars are compiled and built by myself. I find out the problem. problem is costructing the object of that class (which have float value) from startApp(). I got my old Jar which was working earlier. There I costruct the object of that class. So now old jar also giving the "Invalid constant Pool entry" Error. Any that float value I am going to change. Still unclear is What the difference construct object inside startApp() block and ouside startApp() block. Anyway Thank you Guys.

Exception with newFixedThreadPool - Illegal constant pool index

Hi,
I got the following exception :
Exception in thread "main" java.lang.ClassFormatError: Illegal constant pool index 1536 for method signature in class file java/util/concurrent/LinkedBlockingQueue

When executing the following line:

What this error mean ?
Thanks

From the javadoc for java.lang.ClassFormatError:

How to construct the constant pool?

Greetings,
I seems to have a little bit of a problem.
I have a text file, generated by the javap -c <class_name> command,
i.e.:
javap -c myClass > myClass.txt
This myClass.txt is the input I've got. I do not have the myClass.class, from which it was generated.
What I wish to do, is to generate, from this text file, a leagal, runnable, class file (i.e., myClass.class).
But, I have problems understanding how to construct the constant pool array.
I have read the VM spec (java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html).
The thing is, that it does not explain how to extract the needed information from the text file.
Can someone assist?
Would appreciate,
Ohad.

Compiled from Hello.java
public class Hello extends java.lang.Object {
    public Hello();
    public static void main(java.lang.String[]);
Method Hello()
   0 aload_0
   1 invokespecial #6 <Method java.lang.Object()>
   4 return

10 dup
11 invokespecial #5 <Method Hello$1()>
14 lconst_0
15 lconst_1
16 invokevirtual #8 <Method void schedule(java.util.TimerTask, long, long)>
19 returnWell in this example, you have opcodes with arguments which are expressed as (for example) "#7 <Method java.util.Timer()>". This describes a constant pool element. I assume #7 refers to the location within the constant pool, and the text description tells you that it's an item of type method, and gives you the method name. So for all arguments expressed in this form, you'll need to reconstruct a constant pool item.

After converting my vid to constant rate with Handbreak, Premire Elements 11 gets choppy

I am using my cell phone SGH-T599 to shoot video. In order for me to edit it I have to convert it from variable rate to constant rate with Handbreak, otherwise the video and sound go out of sync. But apparently there is something wrong with the conversion settings because when I start to edit it doesn't run smoothly, the indicator bar skips and gets stuck. For example, I can not simply move the bar forward to speed up ahead. This makes editing extremely difficult specially if I want to make a cut in the middle of a sentence etc. Is there a way of fixing this, perhaps lowering the frame rate? I I've included a snapshot of both Handbreak and MediaInfo.

elpepin
When you are doing your HandBrake variable to constant frame rate, use the H.264 (x264) Video codec under the Video Tab.
I typically replace "Chapters" with seconds.
Container = Mp4
Leave the Picture Tab as is.
Head for the Video Tab.
Video Codec = H.264 (x264)
Dot the Constant
Dot the Constant Quality leave at 20 RF
Uncheck web optimize
Leave Presets at Regular/Normal
Leave the Audio Tab as is.
Guideline for now is to make only the changes necessary - change a variable frame rate to a constant one.
By the way, why are you using a HandBrake Average Bitrate = 1500 kbps (kilobits per second) when the source is 12 Mbps (megabits per second)?
Hit the Start Button at the top left of the workspace, and wait for the "Queue Finished" in the progress bar at the bottom left of the workspace.
Have you done that?
Please give it a try and then let us know the results.
Thanks.

"Illegal UTF8 string in constant pool"

I'm running a jsp application on JRun 3.1 with an Appache web server. Every once in while I get this error when trying to access a jsp. "Illegal UTF8 string in constant pool".

Class format error: Invalid constant pool tag found

I am simply attempting to create an instance of an object and I get Class format error: Invalid constant pool tag found. Does anyone know what this means and how to fix it?
Thanks.

If you're compiling with J2SDK 1.4 or higher, you need to use "-target 1.1" on the javac command line.
Also make sure you're not using any float constants such as 1.0 in your code.

Question about String constant pool

Is there is any function available to find how many Sring literal in String Constant pool

Well, there's stuff like BCEL.
But it may not do what you want.
Why do you want to find out what's in the constant pool?

Reflection error (Illegal constant pool index)

Heya,
I use reflection to invoke Java classes and I get Error:
java.lang.ClassFormatError: AppendToElement (Illegal constant pool index)

// AppendToElement is name of class I want to invoke
I have bunch of classes from someone else, which I need to invoke and I get this error for all of them. When I invoke classes written (and compiled) by me, everything is OK.
It seems that the problem is that, these external classes were compiled with different version of Java. As they were written by someone else and I don't have source code, I can't recompile them.
Is cause of that problem, different JVM versions ? Is there a way how to correct it on runtime ?
Thanks,
Michal

The problem isn't one of versions. The files have become corrupted somehow. I suggest you ask for another copy.

Illegal constant pool index ????

Hi
I wrote a hello world program using J2ME with a view to writing a game for a mobile phone. I'm a C++ programmer and have never looked a java befor so I have no idea what is going on under the sheets.
The hello world program is called Welcome (straight out of Sun's J2ME book). It seemed to compile ok and left me with a file called Welcome.class
Following the instructions in the book and working from the Command Line on WindowsXP I typed
d:\preverify ....etc
I got the following
Error preverifying class Welcome
Class loading error: Illegal constant pool index
I've double checked everything and can't find a problem - any ideas?
Cheers

Resolving constant-pool of clazz Luicc/access/fileadministration/AdminFileV

Hi,
can anyone help? I have this problem whenever I import the uicc.access.fileadministration into the Eclispe 3.1 (with JCOP plugin) and building my project.
The full error string is "resolving constant-pool of clazz Luicc/access/fileadministration/AdminFileView; failed: no such clazz Luicc/access/UICCException;"
It's weird because the uicc.access.UICCException is right there & it can be build successfully (without the fileadminstration package). But when I import the uicc.access.fileadministration package & build the project, the build errors appear.
Many Thanks!!!
Eric

Hi,
Thanks for your reply.
I have tried to put the export file structure in the build path, but I am still getting the same error:
resolving constant-pool of clazz Luicc/access/fileadministration/AdminFileView; failed: no such clazz Luicc/access/UICCException;
Can you pls be specific on the steps to include the export file into the build path? I could be getting the steps wrong. Otherwise, do you have any suggestions?
Thanks again.
Eric

Bt the way, there could be another tricky issue. If one uses CVS and checks
in ejbjar without setting -kb on it, the ejbjar that is cheked out will be

at least for default CVS settings.

It looks like a malformed class file. Run the verifier (or javap) against
that class. Turn off JAR compression. Transport files via ftp with the"bin"
setting. etc.
