Peter Hull commented on NETBEANS-3900: -------------------------------------- I'm going to take that as a positive. I apologise, it wasn't clear from my comment but the changes here are in addition to the ones I did for NETBEANS-1428 which I thought would only help Windows and be neutral for everything else. It's possible that just recompiling fixed something (a library or ABI issue) - as far as I can tell, the native code is not rebuilt by Jenkins (the libraries are dated approx 2017) Anyway, can you tell me, did you see any error lines starting "*** PROFILER INTERFACE Error request for method XXX which is not known" in the NB output tab? Would you mind continuing to use this version for a while to check that the problem doesn't recur? I hope that I can get fixes for this and NETBEANS-1428 merged in the NB 12.0 window.
