Netbeans User 2019 commented on NETBEANS-5129:
----------------------------------------------
In context of Tools > Options > Editor > Hints
There is no exact steps to reproduced, but I think that I open new issue:
- to be deactivated all hints and retested with and with and without nb-javac
as seems that many issue like this is connected nb-javac, but It could be even
possible that hints are not revised at all from start and even it is possible
that could be ticked to run by import from prior version of Netbeans, but it is
e.g. so supported in new version
- additionally even turn off nb-javac does not fix issues like these, because
it seems that that states is ignored and nb-javac is still somehow in use ...
so only option is to uninstalled completely (so to see in notification request
for intallation)
- additionally to be added even new feature to reset all Hints to default
