Hard to fix without a reproducible test case.

Just editing sources.
Comment 4 Jesse Glick 2015-10-13 18:48:35 UTC
This is several years old, and is part of NB sources, so surely you could at least introduce better diagnostics so that the next time it happens you will see what is wrong. You are never going to get a reproducible test case when the bug is that while making extensive edits to Java sources, at some point for no clear reason the IDE starts throwing errors.

As of right now I had 2 instances of the error.

One using the netbeans hints, and one manually.
The issue _seems_ to be recursive type variables, but I can't imagine that being _that_ rare.

One class in Querydsl has the following class signature:

public abstract class ProjectableSQLQuery<T, Q extends ProjectableSQLQuery<T, Q> & Query<Q>>

Strange thing is, I can't recall having encountered this, but at least for the time being I can reproduce it.

My exception report is
It shows about 3 errors, 2 with the hint system, one with manual casting

If there's anything I can do let me know.
