Issue:
Trying to start PPM app, an error is thrown in app-system log:
 
Unrecognized VM option 'PrintGCTimeStamps'
Unrecognized VM option 'PrintHeapAtGC'
 
Cause:
This is caused by outdated JVM parameters.
If you recently upgraded Java to a higher version, some of the options will no longer be the same, this is expected.
Resolution:
  1. Open the server's properties.xml, and remove the JVM parameters above from the application server section.
  2. Then save the file and run the command to start the app service again.
