Reason was that it tried to invokeInterface whereas a bridge redirects to a local (virtual) method.
The local method was flagged incorrectly as the same type as the bridger which would be interface, hence the error

They worked in my simple, void test example

The Optional annotation is parameter, not type bound

E.g. IIngredient has a method that accepts an IItemStack, which is a sub-interface

TODO: Verify that the access check is correct

- Fixed a number of bugs
- Upgrading build system to a more uniform system
- Improving error output (for IDE)
- Changed parser to generate line offsets differently (easier for IDE to process)

- Added support to have a native method both as operator and named method

- Fix getters for globals not having their corresponding fields registered correctly in the native implementation
- Added java sources for JavaScripting

- Fix default constructor not working properly
- Fix integration classes without exposed constructor being instantiable if they have a default (non-exposed) constructor
- Fix extern methods failing validation

- Fixed constructor support for native classes
- Added project for maven build
- Added missing StdLibs.zip
