java.lang.UnsupportedOperationException

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • I am running Jenkins 1.486 on an OpenSUSE linux with various plugins (see attached System_Info.pdf for full list). I have 2 Windows slaves attached on which I run FLEX build/analysis/unit-test/flexcover. (This is a follow on from https://issues.jenkins-ci.org/browse/JENKINS-15593 - and has the workaround which includes "c:\Program Files\Java\jre6\lib\endorsed\xercesImpl.jar" to prevent exceptions). I have one slave with: java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing) the other uses: java version "1.6.0_35" Java(TM) SE Runtime Environment (build 1.6.0_35-b10) Java HotSpot(TM) Client VM (build 20.10-b01, mixed mode, sharing) The issue occurs on both. I connect both slaves to the master using slave-agent.jnlp For static analysis, I use FlexPMD which produces pmd.xml and cpd.xml files. Whenever I try to publish a cpd.xml file (from either slave), I get the following exception: [DRY] Collecting duplicate code analysis files...
