I'm facing with this strange error after script compiles successfully but fails

Here is the reproducing script:
{code:java}
@CompileStatic
enum E {
E1{
// int value = 1
int getValue() { 1 }
}
int getValue() { -1 }
}
{code}
If you use an overriding method, all is working fine. But replacing method with
local field causes an error above. I think it is {{@CompileStatic}}-specific
error, because without this annotation both versions are loaded successfully.
