Summary: ConcurrentModificationException during gc run
Key: OAK-187
URL: https://issues.apache.org/jira/browse/OAK-187
Project: Jackrabbit Oak
Issue Type: Bug
Components: mk
Reporter: Michael Dürig
I sporadically encounter a {{ConcurrentModificationException}} when building
with {{-PintegrationTesting}}. This happens while the {{JcrTckTest}} suite runs
and is only printed to the console. No tests fail.
