why the CDT appears here, eludes me -- but i got used to CDT meddling everywhere no matter whether a CDT project is being edited or not (after all, those inexplicable Workbench rebuilds tend to suddenly open a CDT console which one get not rid of unless restarting eclipse).

Comment 1 Noopur Gupta

Moving to JDT Core for the NPE:

java.lang.NullPointerException
        at org.eclipse.jdt.internal.core.search.JavaSearchScope.getPath(JavaSearchScope.java:474)
...

Comment 2 Dani Megert

2016-05-05 12:54:22 EDT

Can you provide a test case?

Comment 3 Jay Arthanareeswaran

2016-05-06 04:44:38 EDT

The NPE looks to be caused by a broken Java element parent-child structure. But can't do much without a testcase.

Comment 4 Eclipse Genie

2020-02-27 08:40:42 EST

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
