Major Description
occurs with 2.5.14 and 2.5.13, but not with 2.5.12 and earlier. reproducible test case attached (testcase.zip).
1) when I try to compile DerivedTrait.groovy with CompileStatic passed via compiler configuration, I get the following NullPointerException:
test_npe# grt DerivedTrait.groovy groovy-2.5.13 >>> a serious error occurred: BUG! exception in phase 'instruction selection' in source unit 'DerivedTrait.groovy' unexpected NullpointerException >>>

2) when the same is compiled WITHOUT CompileStatic, I still get the error, although a bit different:
