Summary: SOlr TestJmxIntegration#testJmxOnCoreReload bug related
to TestHarness
Key: LUCENE-4210
URL: https://issues.apache.org/jira/browse/LUCENE-4210
Project: Lucene - Java
Issue Type: Bug
Affects Versions: 3.6, 3.5, 3.4
Reporter: Emanuele Lombardi
Using zabbix to monitor my Solr instance I noticed that after core reloading
the Mbeans have disappeared. There is a test ->
testJmxIntegration#testJmxOnCoreReload used to check Mbeans presence after core
reload. The test is wrong because TestHarness sets core name to null on
creating the core for the first time (CoreContainer#initialize) so his Mbeans
have jmxRootName="solr" (JmxMonitoredMap#line61). Once the core is created it
sets coreName = "" causing new Mbeans to have jmxRootName="solr/"
So after first core closing only MBeans having name "solr" are removed and
only MBeans with name "solr/" persists on JMXServer. This test is fake.
Step to reproduce test fail
1) Apply TestHarness patch
2) Run the tests
