  • Even after clearing the temporary folders, the portal does not start up properly after installing a new hotfix:

Environment

  • Liferay DXP 7.3

Resolution

  • For some reason, some of the files or entire folders within osgi or Liferay home could become corrupted during hotfix installation.
  • In this case, the above errors were resolved by replacing the core folder within osgi.
    • Please download a new vanilla instance of DXP, apply the necessary hotfix, and swap out the corrupted bundle's osgi/core folder with the osgi/core folder from the new instance.
    • To prevent further challenges, please take a backup first in case a rollback is necessary.

Additional Information

  • Users can always look at the hotfix structure, which they can see if they try to unzip or simply open in archive mode, to confirm which files would be impacted during the installation or reverting of a hotfix.
    • In this case, for example: 
      { $LIFERAY_HOME }\patching-tool\patches\liferay-hotfix-xyz-7310.zip\binaries\MODULES_BASE_PATH\Core
