Eric Milles commented on GROOVY-9695:
-------------------------------------
I'll have to look closer, but when you extend a class you change the nature of
"this" and there are open issues for this same thing when the field is an
instance field. As a workaround, you can add a qualifier to "PATTERNS" or make
the field protected or add @CompileStatic to the method. The static compiler
path adds private access bridge methods which the dynamic compiler does not.
