    Description

      The following test hung in the 2017-07-07 JDK10-hs nightly:

      com/sun/jdi/RedefineClasses.sh

      Here is a snippet of the .jtr file:

      ----------System.out:(27/1343)----------

      The test machine is:

      Intel Xeon 2893 MHz, 2 cores, 15G, Win32 / Windows Server 2012 R2 Standard,

      so it is not wimpy. Based on the output the test was running
      and making progress. The test timed out at 48 minutes.
