Editor closing causes NullPointerExceptions in Linux Eclipse
vorpane opened this issue · 2 comments
Hi,
I have installed Glance in Eclipse 4.1 (Juno) at Linux (Debian v 6.0.6). I opened glance bar and a java file. I entered some word into Glance ant it's occurences were found.
But then I right-clicked on the tab related to opened java file and selected "Close". In error log I got "Unhandeled event loop exception" from org.eclipse.ui. NullPointer (stack trace below). From then on, many actions I did including usage of Error log view and opening the closed java file resulted with more Error log messages with NPE. Also, the Glance stopped finding the words it should have.
I have an RCP application that also uses glance, and it has similar problem on linux. However, on Windows 7 Proffesional, no such problem occurs.
Also, none of this happens if once closes an editor with the "x" sign, instead of right-click and Close. Only the Close (and Close All) causes this.

I get the same exception sporadically with glance 1.2.1.201702271753 in eclipse 4.6.3.
I did not close any tabs when the issue occurred last, but I may have closed a split editor shortly before it happened.
The issue is particularly annoying because eclipse is frozen afterwards. It seems to be still processing the event queue, so it's not marked as not responding, but the UI is longer updated. The only solution seems to be killing and restarting eclipse.

I hit the same error in Linux Eclipse by doing this:
- Open glance and search any word
- Right click the tab on the active editor and select 'Close'
After this glance stops working until eclipse is restarted.
