Robert Stupp commented on CASSANDRA-12133: ------------------------------------------ [~limonad], you can safely ignore this message (see [OHC issue|https://github.com/snazy/ohc/issues/17]). It's fixed in OHC 0.4.4 (not sure why I forgot to submit a patch for that until now).. Using this ticket to upgrade OHC - but not in 3.0.x as it's just an "annoying" message. ||trunk|[branch|https://github.com/apache/cassandra/compare/trunk...snazy:12133-update-ohc-trunk]|[testall|http://cassci.datastax.com/view/Dev/view/snazy/job/snazy-12133-update-ohc-trunk-testall/lastSuccessfulBuild/]|[dtest|http://cassci.datastax.com/view/Dev/view/snazy/job/snazy-12133-update-ohc-trunk-dtest/lastSuccessfulBuild/] > Failed to load Java8 implementation ohc-core-j8 > ----------------------------------------------- > > Key: CASSANDRA-12133 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12133 > Project: Cassandra > Issue Type: Bug > Components: Core > Environment: Ubuntu 14.04, Java 1.8.0_91 > Reporter: Mike > Priority: Trivial > Fix For: 3.x > > > After enabling row cache in cassandra.yaml by setting row_cache_size_in_mb, I > receive this warning in system.log during startup: > {noformat} > WARN [main] 2016-07-05 13:36:14,671 Uns.java:169 - Failed to load Java8 > implementation ohc-core-j8 : java.lang.NoSuchMethodException: > org.caffinitas.ohc.linked.UnsExt8.<init>(java.lang.Class) > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
