- StackOverflowError when use anonymous class with generics.

- Using with method with a closure that references a protected property produces ClassCastException

- GrapeIvy downloads wrong artifact for non-default conf when artifact name is not the same as the module
- void[] return type causes compiler to fail
- Compiler error for @CompileStatic and @NotYetImplemented combination
- Bug joint compilation in ant task groovyc: classpath not set
- CLONE - Conflict between @Generated and @Delegate

- Groovyc fails to correctly propagate classpath entries to javac when run under JDK 11
- Incorrect compile time access error is raised when using @CompileStatic and/or @TypeChecked
- Calling super.toString() with @TypeChecked or @CompileStatic will throw java.lang.StackOverflowError

- AST for precompiled classes loaded from the classpath does not contain constructor annotation information

- Add @ClosureParams to closure input parameter of Sql.withBatch(...)
- Better signature for ResourceGroovyMethods.traverse(File, Map<String, Object>, Closure) (and overloadings)
