Description

@CompileStatic breaks assignment for code like

@groovy.transform.CompileStatic
class StaticClass {
    StringHolder holder = new StringHolder()
    String str

    StaticClass(String s) {
        str = holder.str = s
    }
}

class StringHolder {
    String str
}

def s = new StaticClass('test')
assert s.holder.str == 'test'
assert s.str != 'test'

The second assert fails because s.str == null. Without @CompileStatic it works correctly (and as java).
