 Description   

Just tried to compile the source with "ant jar" under jdk 1.5.x because the new release 1.3.2 seems to be compiled wiht a newer version ("Bad version number in .class File").

I got the following:
--------------------------------------------------------
compile_main:

Do you have any suggestions how to solve the problem ?.

Thanks

Are you using the newest version of JDK 1.5? There are some generics-related bugs in early versions of the compiler.

There are special JDK1.4 binary packages if that's what you need. The source must be compiled with Java 5+.

Thomas,

It compiles for me with java version "1.5.0_13"

if i remember correctly, you need to have Java version higher than 1.5.0_06 - there was a bug in compilation of generics in _06 so you need to get a compiler higher than that.

Here's the output of my java -version call:
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05-237)
Java HotSpot(TM) Client VM (build 1.5.0_13-119, mixed mode, sharing)

Thanks for the response. I tried with 1.5.0_06 then with 1.5.0_07 - failed; then I downloaded the last 1.5 sdk Version "1.5.0_16". This one was able to compile the source.

Hi,

I am not even trying to compile the source but when I start my process which uses QuickFIX/J 1.3.2 then I also get:

Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file

I have JDK 1.5.0_16. When using JDK1.6.0_07 the error does not occur.

Any thoughts?
Best regards,
Chris

It's possible the code was accidentally compiled with Java 6 instead of Java 5. I'll check into it. Thanks for the report. I'm surprised no one else has reported this issue.
