Eric Milles resolved GROOVY-5776.
---------------------------------
Resolution: Fixed
> Accessing static property in closure of sub-class creates a "serious error"
> ---------------------------------------------------------------------------
>
> Key: GROOVY-5776
> URL: https://issues.apache.org/jira/browse/GROOVY-5776
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.0.4, 2.4.0-rc-1
> Reporter: Andrew Eisenberg
> Priority: Major
>
> Discovered in GRECLIPSE-1492. Compile the following snippet in Groovy 2.0.4:
> {code}
> class TestappService extends ServiceBase {
> def foo = { params ->
> def param = params[TESTAPP_IDX]
> return "Hello, ${param}"
> }
> }
> class ServiceBase {
> static final String TESTAPP_IDX = 'index'
> }
> {code}
> You get this stack trace:
> {quote}
> >>> a serious error occurred: BUG! exception in phase 'class generation' in
> >>> source unit 'foo.groovy' Trying to access private constant field
> >>> [ServiceBase#TESTAPP_IDX] from inner class
> >>> stacktrace:
> BUG! exception in phase 'class generation' in source unit 'foot.groovy'
> Trying to access private constant field [ServiceBase#TESTAPP_IDX] from inner
> class
