Description

It seems to occur when a property in the object has a name where the 2nd character is uppercase. It happens with both @ToString and @EqualsAndHashCode. Example:

@groovy.transform.CompileStatic
@groovy.transform.ToString
class MyClass {
    List<String> aList
}

Groovyc: java.lang.ArrayIndexOutOfBoundsException: Internal compiler error while compiling C:\myProject\src\MyClass.groovy
Method: MethodNode@781552568[java.lang.String toString()]
Line -1, expecting casting to java.lang.Object but operand stack is empty
