NullPointerException in XvfbBuildWrapper.setUp when configured without node label restrictions

XMLWordPrintable

      I get the following traceback when running a job with configured xvfb plugin and no node labels:

      FATAL: null
      java.lang.NullPointerException
      at org.jenkinsci.plugins.xvfb.XvfbBuildWrapper.setUp(XvfbBuildWrapper.java:568)
      at hudson.model.Build$BuildExecution.doRun(Build.java:153)
      at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:518)
      at hudson.model.Run.execute(Run.java:1706)
      at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:43)
      at hudson.model.ResourceController.execute(ResourceController.java:88)
      at hudson.model.Executor.run(Executor.java:231)

      The line reads:

      if (assignedLabels != null || assignedLabels.trim().isEmpty()) {

      shouldn't that be && ?

      A workaround is adding a label (i.e. master)

          The required code should use "&&", but it also must negate the isEmpty() (to get those that are not empty):

          if (assignedLabels != null && !assignedLabels.trim().isEmpty()) {
   // Do something using the label
}

          This slipped in 1.0.11, sorry about that. Thanks for reporting and suggesting the fix. Version 1.0.12 is released that fixes this and should be available soon on the update center.
