 Description  « Hide
When running the datanucleus:enhance command twice, the build results in a java.lang.Verify error:

Normally, one wouldn't run datanucleus:enhance twice manually, but when building a project using the "package" or "install" commnands (which may very well be run without doing a "clean" first), the datanucleus:enhance command is also run, and therefore the build fails with java.lang.Verify.

This issue can also be reproduced with the "datanucleus:enhance-check" goal.

Note that this issue appears to be specific to having a source/target setting in maven-compiler-plugin of 1.7. When changing the compiler source/target to 1.6, the issue goes away, even when running on JDK7.

I'd refer you to NUCENHANCER-81 since we don't explicitly support JDK1.7 or higher. Obviously you could easily contribute your time to add support for ASM v4 (see NUCENHANCER-81)
