-----------------------------------

             Summary: Memory leak related to org.jboss.threads.JBossThreadFactory
                 Key: JBREM-1340
                 URL: https://issues.jboss.org/browse/JBREM-1340
             Project: JBoss Remoting
          Issue Type: Bug
          Components: jmx remoting
            Reporter: Adrián López


We have a memory leak when using the jboss-cli-client JAR inside of Jolokia.

Jolokia uses remoting to connect to the JMX of several JBoss servers. After running for some days, the Old Gen memory space reach 100%.

A heap dump analyzed with Eclipse MAT returns:

{code}
One instance of "java.lang.ThreadGroup" loaded by "<system class loader>" occupies 377.517.248 (87,28%) bytes. The instance is referenced by org.jboss.threads.JBossThread @ 0xe0a81ef0 HTTP-11 , loaded by "org.jboss.modules.ModuleClassLoader @ 0xe04ffe20". The memory is accumulated in one instance of "java.lang.ThreadGroup[]" loaded by "<system class loader>".

The stacktrace of this Thread is available. See stacktrace.

Keywords
java.lang.ThreadGroup[]
org.jboss.modules.ModuleClassLoader @ 0xe04ffe20
java.lang.ThreadGroup
{code}

I have created also another [issue|https://issues.jboss.org/browse/JBTHR-72] to jboss-threads, but looks the problem is not there.

Same for [Jolokia|https://github.com/rhuss/jolokia/issues/401]

Thanks
