When attempting to start the Foglight Management Server (FMS), it fails to do so. When looking at the FMS startup output (from the command line), the following can be seen:
YYYY-MM-DD HH:MM:SS.000 DEBUG [native] Loaded Java VM shared library D:\Quest_Software\Foglight\jre\bin\server\jvm.dll
Error occurred during initialization of VM java/lang/NoClassDefFoundError: java/lang/Object
This can be caused by a corruption of the JRE folder within the Foglight Installation directory (<FGL_HOME>\jre\). Replace the JRE directory with a JRE folder from a working equivalent FMS installation (ensure to make a backup of the JRE folder on the problematic FMS before making the copy from the working environment).
