What happens when an exception occurs at finalize method ?

What happens when an exception occurs at the time of cleaning objects in finalize methods?
Will program crashes?

1.) Why don't you try it? You can simply throw your own exception.
2.) For this kind of questions the JVM specification is a good resource, for your concrete problem the chapter about finalization might be interested (look for the sentence starting with "If an uncaught exception ...").

What happens if the exception occurs in a thread when it has a lock

what happens if the exception occurs in a thread when it has a lock
on object. Is the lock released ?

Rastogha wrote:
ok so lock is released if we are putting code in try-catch block. . right ?
1) But suppose what abt runtime exceptions which i am not catching. It doesn't matter what kind of exception it is. The lock is released when control is transferred outside the sync block.
2)Also the thread will be suspended in both the cases or not ( both cases mean for runtime exception and checked exception)Again, the kind of exception doesn't matter. Whether you're in a sync block or not doesn't matter: When an exception occurs, control transfers to the nearest catch block that can handle it. If you don't provide a handler for it, the thread terminates.
If something is not clear, post code that shows the specific situations you're curious about. Make sure you use the CODE button or [code] and [/code] tags.

What happen when an error occurs during Snapshot-Refresh?

Hi,
I would like to know what happens, when an error occurs
during a refresh (COMPLETE-REFRESH) of a snapshot?
Is there a possibility for exception-handling??
During a complete refresh the data in the snapshot will be deleted an the requested new from the master-side. Now when
an error occurs during the refresh what happens with the "old" data of the snapshot??? Will it be lost?
Thanxx

Each thread has its own error state. To get the results for a thread (including error result), you need to have a wait step which waits for it. If a thread has an error and you wait for it, you will get the error at the wait step that waits for it.
If your main thread has an error and you want some worker thread to exit, you should add code to the cleanup of your main thread's sequence which signals the worker thread to exit (you should already have some sort of mechanism for signaling the worker thread to exit (there are many ways to do this, for example, a boolean variable passed by reference to the new thread's sequence, or a TestStand notification).
If your main thread is getting an error, but is stuck inside a step, that problem is probably specific to something your code is doing, that is not the normal behavior of TestStand. You will need to provide more details or an example sequence in order for us to better understand what is happening.
Hope this helps,

What happen when an error occur when there are 2 threads running ?

Here is my execution :
My MainSequence calls another sequence in a new thread. This sequence call a VI continuously
When an error occur in the MainSequence, nothing happen : The step with the error in Mainsequence is still in execution state (with the arrow in front of it) and the VI in my 2nd thread is still running. All I can't do is terminate all thread
Is this behaviour normal ? What is the mean to solve this problem (maybe calling the 2nd sequence in a new execution ?)
Thanks for your answer
Laurent

What happens when HTTPS communication fails during certificate check?

Hello Experts,
I have a scenario where a Bapi functionality(server proxy) is exposed as a webservice .
So scenario will be SOAP -> XI -> Proxy (calls a BAPI)
Here we are going to use HTTPS (SSL).
I would like to know :
What happens when a check for certificate validation fails in XI? It may be due to invalid certificate, expired certificate or a request from unauthorised user-
- Will it be raised as a exception and we need to do some configuration to inform it back to Sender?
- Will the message fail in Moni with red flag ?
- Alerts will be created ?
Please share your experiences and expert sugestions.
Thanks in Advance!!
Regards,
XI Queries.

Hi Abhishek,
Thanks for the reply. I will keep this in mind and design the scenario & error handling accordingly.

What happened when multiple audio players start at the same time?

Hi,everyone!
I am developing a game, using JMF to play sound.
These sound are stored in mp3 files.
In order to decode mp3 files, I installed JMF and mp3-plugin( jmf-2_1_1e-windows-i586.exe , javamp3-1_0.exe).
In the Game, a background music play back repeatly.When EndOfMediaEvent happened, I setMediaTime(new Time(0)) and then start().It works well.
There are several sound-effects,may start at any time,
so 2 or more sounds may play back at the same time,
and then Strange things happened.
Those sound-effects, usually short, can not play back inextenso.
They lose some beginning part, the length of the part is not constant.
i.e. Audio should start at MediaTime 0, but now they start at MediaTime x, x >= 0,
not only that, sometimes, Audio process bar runs, but no sound heared.
I do not know what is happening.
So please help me, thanks a lot.
The way that I use Players:
initialize:
create realized players from mp3 files
prefetch them
finalize:
deallocate not null players
then close them
using:
player.setMediaTime(new Time(0))
then player.start()
My Environment:
Windows XP, java 1.4.10, JMF2.1.1, MP3-plugin1.0

This is very strange, difficult to guess the cause... never had such an issue. Normally when the object to which the audio is attached disappears the audio stops. So in your case going to a next slide should stop the audio of the previous slide. Same with object audio.
Do you have the different audio clips (one per slide) in the Library? Could you try to delete the audio on the slide and drag it again from the Library to see if you have the same result? And what happens when you attach the audio clip to an object on the slide (you can create a totally transparent rectangle with no stroke that will not be visible to attach the audio).

What happens when error record

Hi ABAP Gurus,
Iam phaneendra can anybody explain in detail
what happens when there is an error record exist while updating a session in session method and in call transaction.
ie, out of 10 records 7th one is error let it be then what happens to 6 redords that 7th record and 8th 9th 10th records.
and also what is assychronous and synchronous
process .thatly in updation.
good answers( helpful answers must be rewarded)
regards,
phaneendra.

Hi,
In Session Method all the 9 records will be updated except the &7th record(error record). u can get the error information in SM35.
In call tranasction method it depends upon the mode(A,N,E). In all screen mode system will stop at 7th record and all the previous 6 records will processed. In No screen mode all the 9 records will be updated except the 7th record(error record). and track the error u have to use BDCMSGCOLL in ur program(for call transaction).
Asyn-- System does not wait for Acknowledgement. but in Syn--- System waits for acknow. For this reson Asyn process is fast as compare to Sync.

What happens when the iPhone needs an activation and it doesn't respond? Then it asks me to restore it but due to an unknown error (-1) the iPhone can't be restored.

Thank you for your response. However, I have done that plenty of times and each time I try to restore my phone, it extracts the software and then when it says restoring with the loading bar, an error message comes up saying an unknown error has occurred.

What happens when buffers fill up?

I guess this is a pretty basic question but my application is here. What happens when a buffer gets full? Does it stop reading and throw an exception or does it keep reading but destroy the information it received at the beginning? They question related to an application where I'd like, when an event is triggered, to store the last 10 seconds on video.

i think you might get an exception (Array out of bound). Somehow it depends on how u implement your buffer.

What happens when you transfer contents?

I have my desktop backed up on a MyPassport Ultra. This computer runs Windows Vista Home Premium. I am in the process of setting up a new laptop with Windows 8.1 which I understand about this || much. What happens when you transfer the contents? I understand that you plug the MyPassport into the laptop and it should direct me how to install what has been backed up. But what will it look like on the new computer? Will the folders be in the same directories? Where will they be stored? And can someone confirm what will NOT be backed up and transferred? I was told it would be programs that I installed, such as Paint Shop Pro, etc.
Would be very grateful for any assistance

Well! That was so much more painless than I thought, LOL. The transfer went well and I had no problems finding the files, but I apparently have not set the rules for what to copy, right. I understand from p.46 of the manual, Backing Up Files, that you select what to copy from the drop down menu under the PC/Dropbox icon. In my case that only offers Acer (C, Data (D, and MyPassport. I chose Acer (C, thinking it copies everything on the computer except program files. But it did not copy a specific category (?) named in this image "Working". Can you tell me what I've done wrong so I can correct it before I lose something? It would be my luck.

What happens when an iPod is synchronized with an iTunes library that is bigger than the available space on the iPod?

What happens when an iPod is synchronized with an iTunes library that is bigger than the available space on the iPod? I did this some time ago. On screen was shown available space somewhat less than 120 GB, but maybe somewhere between 10 and 20 GB more in the library. I had to get the iPod updated anyway, so I did proceed. However, afterwards the total content of the library was only about 110 GB. Now I wonder what did actually happen. Was the first sign only corrected for double copies of the same files or lost files or where files deleted from iTunes? And if files where deleted from iTunes, were they also deleted from my computer?

Same as you would if you bought a pc; copy everything from your old computer to your new one. Then you can just sync everything from the new computer, as you did with the old one.

What happens when multiple users access the same servlet?

Do the users share all the same resources? Or is a new process generated for each user? I have a servlet that builds a string to return to the user and I only have myself to test, so I can't really see what happens when many users access the servlet. Is there a possibility that the string will get screwed up, like when dealing with multiple threads, or do all the users get their own resources and I don't have to worry about that?

huh? if you can point a test servlet at it, you can point a browser at it (even if the servlet does not serve html it will run)
try pasting the servlet URL into a web browser
refreshing multiple browsers repeatedly could provide a manual test
