Description Andreas Sewe CLA 2016-02-04 04:01:20 EST 
Installed AERI from the head update site this morning. After a while, I noticed this NPE in the terminal I used to start Eclipse:

The issue can happen when org.eclipse.epp.logging.aeri.core.SystemControl.getSystemContext()is called from different threads.
It isn't easy to reproduce it. You can do it by debugging AERI and setting a breakpoint to SystemControl.java, line 40:

registerHandlers(SetSendModeHandler.class, ResetSendModeHandler.class);

After that, you need to open the Error Reporting preferences page and click the "Configure projects..." button.

https://git.eclipse.org/r/67798 (bug 488868) fixes the issue.
