Looks verrryy much like bug 471611 Any chance you try it with a recent build (> 2015-07-12)? *** This bug has been marked as a duplicate of bug 471611 ***

I updated Java Development Tools 3.11.0.v20150722-1000 from the maintenance update site. I get the same error as before but I'm surprised that the JDT core and JDT ui bundles are the same as before.

Sorry, external annotations were a motivation for that feature, but enabling annotation based null analysis suffices to enter this code path. > > Looks verrryy much like bug 471611 > > > > Any chance you try it with a recent build (> 2015-07-12)? > > I updated Java Development Tools 3.11.0.v20150722-1000 from the maintenance > update site.

We haven't yet started back porting any fixes into the maintenance stream. So you'd need to use some 4.6 build, perhaps from http://download.eclipse.org/eclipse/updates/4.6-I-builds

Sorry. EPP packages are not compatible with the I build. I tried several different update paths this morning but it did not work. I'm on the run now.
Verified for Eclipse Neon 4.6 M1 Build id: I20150803-2000 (by comparing the stack traces)
