Eclipse M8: On certain projects if I try deleting a java file through the package explorer I get an NPE. If I try and deleting through the navigator it works fine: ---------------------------------------------------------------- java.lang.NullPointerException at

Strange, since the element to be deleted should never be null. Nikolay, do you have a reproducable test case for this. This would be really help.
I debuged the workspace and the problem is that the project I am using is called "Common (11070200)". The "(" is causing getHandleFromMemento() not to work.
Nikolay, thanks for debugging the workspace.
The method comes from JDT/Core. Philippe, can we address this for M9 ?
We did have problems in the past with parenthesis in project names (during indexing), looks like this is another one of these...
this is probably a duplicate of Bug 47815
Indeed, smells like dup. *** This bug has been marked as a duplicate of 47815 ***
