Several issues with this report: This version eclipse.buildId=3.8.0.201606301029-RELEASE-e46 indicates that you are not using an original distribution from Eclipse.org but a variant patched for STS. Please tell us the exact version number of plugin org.eclipse.jdt.core better understand which software exactly you are running. Seeing the 201606... time stamp this should be s.t. like 3.12.0.v201606 ... tentatively setting version to 4.6 (=jdt 3.12) but the 3.8.0 prefix above makes me wonder. Target milestones are set by developers, not reporters (unless you provide a good quality patch :) ). Importance 'blocker' is probably inappropriate (all compiler bugs are very important for those affected, but marking all as blockers doesn't help prioritize). To actually perform any investigation we need a reproducing example (source code). Could you please provide such? It may be our lucky day, because the exception looks very similar to bug 496675, which has been fixed in master and is pending for backport to 4.6.1, but line numbers don't match, likely due to source changes made for STS. You are invited to test a 4.7 M1 build of Eclipse SDK, but obviously we cannot make any statement about when our fix becomes available via STS.
We clearly need more information to do anything here. When you have more details, feel free to reopen.
Verified for 4.7 M6.
