Comments
From submitter: I tried, just like you did, using javac to compile my source and the result is ok. I found this behaviour when running the code as eclipse java project. The class files included originated from an eclipse compile. When running those from the bin folder $ cd bin $ java de.thomasvogler.xxx.Main the crash happens. Probably eclipse compiles the source different? If i find the time, i will try a clean eclipse install and report an eclipse bug report.

This is expected behavior. Closing as NAI.

[~psonal] Can you find out from the submitter how the code is compiled? It doesn't appear to have been compiled with javac.
