--------------------------------------
Attachment: TestHarnessPatch.txt
> 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: 3.4, 3.5, 3.6
> Reporter: Emanuele Lombardi
> Labels: CoreContainer, CoreReload, JMX, patch
> Attachments: TestHarnessPatch.txt
>
>
> 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
