Paul King commented on GROOVY-7989:
-----------------------------------
This seems to be already fixed on the master branch (targeted for 2.5) but not
the 2_4_X branch.
> VerifyError when calling protected method #clone()
> --------------------------------------------------
>
> Key: GROOVY-7989
> URL: https://issues.apache.org/jira/browse/GROOVY-7989
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 2.4.5, 2.4.7
> Environment: Ubuntu Precise
> x86_64 arch
> Java 1.8.0_91
> Reporter: Nick Stokoe
>
> Running this demo code reproduces the error:
> {code}
> import groovy.transform.CompileStatic
> @CompileStatic
> class Foo {
> static {
> List list = []
> list.clone()
> }
> }
> {code}
> This works when @CompileStatic is off, but when it is on, the compiler
> throws. It seems suspiciously low level - yes, Map#clone is protected and
> therefore inaccessible in this context, but obviously one would want
> something more user-friendly than this, not least because it doesn't indicate
> *where* the error is, so finding it can be tricky:
> {code}
> Caught: java.lang.VerifyError: (class: Foo, method: <clinit> signature: ()V)
> Bad access to protected data
> java.lang.VerifyError: (class: Foo, method: <clinit> signature: ()V) Bad
> access to protected data
> {code}
