Troubleshooting: Bad version number in .class file

The Service Manager server requires a proper Java run-time environment (JRE) to start. If the server does not start and you receive a "Bad version number in .class file" error message, then your system does not have the proper version of the JRE installed.

Service Manager installations on Windows should already include the proper JRE necessary to start the server. If you receive this error on a Windows system, you may need to reinstall the server to get the proper JRE version.

Installations on Linux require you to provide your own JRE. Install a proper version of JRE as directed by the HPE Service Manager Installation Guide and the HPE Service Manager Support Matrix.
