--------------------------------------------
Summary: NullPointerException while compiling a trait
Key: GROOVY-10143
URL: https://issues.apache.org/jira/browse/GROOVY-10143
Project: Groovy
Issue Type: Bug
Components: Static compilation
Affects Versions: 2.5.14, 2.5.13
Reporter: Sergey Kachanovskiy
Attachments: test_npe.zip
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:
{noformat}
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
>>> stacktrace:

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