  • there will be displayed an error several times in the log, causing a long stack-trace.

Environment

  • DXP 7.3 SP1

Resolution

  • The error thrown was not supposed to be an error, but a warning message instead. It was displayed like this back in Liferay Portal 6.2 and it was observed that it turned back to a single-line warning message in recent versions of 7.3 as well as the versions of DXP 7.4.
  • A simple upgrade should resolve the behavior and you should expect to see a line like this:
 WARN  [http-nio-8080-exec-3][PortalImpl:7505] Unable to impersonate fPisUClvBcRej4ZdMR5+sw==sk because the string cannot be decrypted
