      Description

      At some point in time, with the increase in the number of builds on Jenkins, we faced a  "Too many open files" exception in Jenkins log.
      Analysis of lsof command output (lsof-jenkins.zip) showed that there are a lot of open files in some projects (Freestyle or Maven type)  created at build completion on Jenkins master with name:

      {$JENKINS_HOME}/jobs/test_project/builds/140/GetJUnitTestResults4300391778772244764.tmp 
      

      I found file with non zero size with the folowing content:

      $  cat GetJUnitTestResults1715785790472604747.tmp
      ▒▒ ♣sr Gcom.hpe.application.automation.tools.octane.tests.junit.JUnitTestResult▒▒▒▒▒▒▒  JdurationJ startedL     classNamet Ljava/lang/String;L ◄externalReportUrlq ~ L

      So I decided that hp-application-automation-tools-plugin leaves files opened after build finish.

      The graph shows number of opened files by jenkins process. The red line is when plugin turned off
