Unsafe & inefficient concurrency in XStream

    • 2.266

    Description

      Related to JENKINS-13154, we are still seeing lots of congestion with Jenkins 1.517 and our builds may still stay tens of minutes in "Waiting for Jenkins to finish collecting data" -phase.

      The place has changed though, now thread dumps show lots of these:

      java.lang.Thread.State: BLOCKED (on object monitor)
      at java.util.Collections$SynchronizedMap.get(Collections.java:2031)
      waiting to lock <0x000000070c6dcfa8> (a java.util.Collections$SynchronizedMap)
      at com.thoughtworks.xstream.core.DefaultConverterLookup.lookupConverterForType(DefaultConverterLookup.java:49)
