I'm developing java maven project in STS (based on Eclipse Juno 3.8.2) and I'm getting following error:
java.lang.ClassFormatError: Incompatible magic value 0 in class file org/eclipse/jdt/internal/junit4/runner/JUnit4TestReference
I think it have something to do with mixed Java versions, but I'm not able to solve it, probably I missed something.
Full stacktrace is:
java.lang.ClassFormatError: Incompatible magic value 0 in class file org/eclipse/jdt/internal/junit4/runner/JUnit4TestReference

I found out, that there is a problem only when I'm trying to run JUnit tests, my project is running fine. I tried to check run configuration and it seems it's ok. I checked project facets too, and everything seems to be ok there too...
Despite having 1.7.0_17 on the command line I think your Eclipse is running on an older version of java. To determine what version of java Eclipse is running on see:
Find out what JVM Eclipse is running on
Then to change the version of java Eclipse is running on see:
http://wiki.eclipse.org/Eclipse.ini#Specifying_the_JVM
Hope that helps.
It seems, that is some general problem with STS (based on Eclipse Juno 3.8.2).
I tried the simplest possible test and it's not working too:

and I'm getting same error in STS (3.8.2), while in STS (4.2.2) everything works fine.
