Some people upgrading from 5.3 to 5.5 may see an error reading “Unrecognized VM option ‘UseCompressedStrings’ ; Error:Could not create the Java Virtual Machine” after zoom service start. Please follow the instructions below to resolve this.
Solution
- While upgrade from 5.3 to 5.5, please do not replace complete newly installed
conf/
directory with backupconf/
directory. - While upgrade from 5.3 to 5.5, only few files need to be replaced namely
metadataspec.xml, preview-server.xml, server.xml
- The files that were modified during 5.3 (for example,
wrapper.conf
) must be merged with the corresponding file from the newly installedconf/
directory. - The remaining files from the newly installed conf/ directory must be retained.
