JavaCard .cap file generation throws IllegalArgumentException

Question

Hi all,
I'm trying to generate a .cap file for some applet source provided externally, and capgen/converter are throwing an IllegalArgumentException when I attempt to generate a .cap (either straight from .opt or using capgen on a pre-generated .jca file). I'm able to generate/run the .cap file from JCOP tools for eclipse, so I'm able to verify it's authenticity.
The output I'm getting is pretty basic even in verbose mode:
C:\projects\MWallet\src>converter -config .\com\schip_select\schip.opt

Cap file generation failed.
conversion completed with 1 errors and 0 warnings.
The opt file I've got should be fairly un-offensive:
-out CAP
-exportpath "c:\JavaCardDevelopment\api_export_files;C:\gp211;.\"
-debug
-i
-v
-noverify
-applet 0xA0:0x00:0x00:0x00:0x04:0x10:0x10 com.schip_select.schip
com.schip_select
0xA0:0x00:0x00:0x00:0x04:0x10 1.0
I've tried with or without the -noverify flag.
I'm using Java JDK Standard Edition (build 1.4.1_07-b02) to run the converter, and compile the source files. And I've tried the converter in the Sun Java Card Development kit 2.2.1 and 2.2.2. I've also tried attaching the jdb.exe to converter to see whats going on, I can see that it fails in a function:
com.sun.javacard.jcasm.cap.ReferenceLocationComponent.addTwoByteOffset()
But can't get anymore information than that. Any pointers to what could be causing this (I frankly don't know where to start) would be greatly appreciated.
Thanks,
James

6A80 is the error which says that there is mismatch between jc version of card and java version.
For Javacard 2.2.1 java version is jdk.1.4.1
But lets not focus on that
I tried to recreate the problem. You were using GP classes to create a cap file so I downloaded GP exp files from
[http://www.globalplatform.org/specificationform2.asp|http://www.globalplatform.org/specificationform2.asp].
Compiled files as
javac -g -classpath .\classes;..\lib\api.jar;..\lib\installer.jar;libs/gp211.jar;libs/jc221.jar {PACKAGE_DIR}\*.javaMy opt file is as
-out EXP JCA CAP
-exportpath C:\java_card2.2.1\java_card_kit-2_2_1\api_export_files;C:\GP211\GP_exportA00000015100
-applet <APPLET_AID> <Applet_DIR>
<PACKAGE>
<PACKAGE_AID> 1.0and called converter command as
converter -config {PATH_TO_EXPORT_FILE}\HelloWorld.optI was able to create the CAP file successfully.
