What steps will reproduce the problem? 1. Run Organize Imports on a Java file This happens only in some cases. I tried this with different files, some files work others don't. When i deleted all imports it worked. After they were there again it failed again. Maybe it happens when there are MANY imports already: Currently it fails on a file with 2 static imports an 68 non-static imports. I have set import-grouping to 9999, which eliminates wildcard imports. -- Error Details -- Date: Fri Mar 15 15:28:35 CET 2019 Message: Internal Error Severity: Error Product: Eclipse IDE

I narrowed it down: The error only happens (on my current test file) when these two imports are present: import com.google.common.base.Preconditions; import com.google.common.cache.LoadingCache; When i delete them and Organize imports they are beeing added as they should. When running it again the arror occurs again.
New findings: The problem might be related to classes beeing on the type filter. For example: import javax.annotations.Nonnull; // while this class or package is on the type filter

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
