[jar caching] - winp.x64.dll access conflicts

    Details

      Description

      Seems that JAR caching also takes DLL files on Windows.
      Thanks to Windows architecture (), it leads to access conflicts, because DDLs may be locked by other process.

      The issue is being heavily reproduced during the process. After several hours, any process termination fails with the FileNotFoundException exception (see the log below).

      Probably, the high frequency of the issue is somehow related to "Cygwin Process Killer" plugin. On my installation it calls additional remote call on the node before any process termination (it is an interim workaround for JENKINS-19156 and JENKINS-20289 in the custom 1.509.4 core build).
