TextUML Toolkit M2a - Java 5 users please read

Filed under: TextUML Toolkit, UML — rafael.chaves @ 12:36 pm

A user has just reported that the TextUML Toolkit M2 build did not work at all for him. Ouch. Thankfully, the user included in the bug report all the information I needed to allow a quick diagnostic: turns out he was using a Java 5 VM, and he was getting exceptions like this:

java.lang.UnsupportedClassVersionError: Bad version number in .class file

 at java.lang.ClassLoader.defineClass1(Native Method)

 ...

I then realized that for the M2 build some of the plug-ins were accidentally compiled having Java 6 as the target platform, and thus wouldn’t work on a Java 5 VM. This is being fixed as I write this, and a new M2a build will be available shortly.

So, for those of you running with a Java 5 VM, please make sure you download the TextUML Toolkit M2a build. Otherwise, if you are using a Java 6 VM, you should be fine with M2, no need to download the build again.

Thanks to Jon for reporting the issue. Keep those bug reports coming!
