Java parser throws exceptions like crazy about canopy

This looks like it was fixed in #23 -- could you have a look at that thread and see if this is the same issue?

By the way, I'd appreciate you not calling things "crazy" when you find a bug in them :)

I'm closing this as fixed, per my above comment. While there are a lot of unchecked substring() calls in the generated code, the one that's really critical is the one generated by the chunk_() function, which allows a match to occur. All other substring() calls are used in TreeNode construction, which should only happen if the parser has succeeded up to the required string offset. It can only do this if leaf matchers like "hello", [world] or . have consumed input without overflowing the offset.

This should now be fixed as part of the v0.4 release; see https://blog.jcoglan.com/2022/04/01/announcing-canopy-0-4/
