Symptoms

After upgrading Fisheye by moving FISHEYE_INST files (Method 2 of the upgrade guide) one or more of your repositories can no longer be indexed properly

ERROR - Problem processing revisions from repo my-repo due to class java.lang.IllegalStateException - Unable to load changeset

Cause

An incorrect value is held in Fisheye's repository cache and is causing the indexer thread to throw IllegalState exceptions.

Resolution

Clearing out the cache will resolve this issue, to do this:

1. Shutdown FIshEye.
2. Remove the contents of the FISHEYE_INST/var/cache directory.
3. Re-start Fisheye.
