[jira] [Commented] (OAK-3221) JournalTest may fail on machine with slow I/O

    [ https://issues.apache.org/jira/browse/OAK-3221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14693436#comment-14693436 ] 

Marcel Reutegger commented on OAK-3221:
---------------------------------------

Only the 1.0 branch is affected, because trunk and 1.2 do not use MapDB anymore.

> [~reschke] reported a failure for JournalTest.lastRevRecoveryJournalTestWithConcurrency() on a test machine without an SSD.
> This test creates 200 threads running lastRev recovery concurrently. Each thread will create a map using MapFactory. The default implementation in 1.0 is backed by MapDB and therefore creates quite a bit of I/O. Even on my machine with an SSD the test takes 11 seconds to run.
