Description

When using @Synchronized('mylock'), but failing to declare mylock in class, compile fails with bug.

    import groovy.transform.*

    @CompileStatic
    class A {
        @Synchronized("mylock")
        void sync() {
        }
       
    }

    def a = new A()

Typical error :

BUG! exception in phase 'canonicalization' in source unit '/path/to/test.groovy' unexpected NullpointerException
