   See #982 (comment), there is a concerte case same as this error, where the root exception for FrameworkEvent Error/ Application error is as follows.

   The reason is that the workspace state is corrupt, and Java language server fails to restore it back. One improvement we can provide is to pop up a notification to ask whether to clean workspace if the extension fails to start due to such kind of Framework Error.

   I was wrong about the parent process watcher being to blame. That just kills the kill -0 process which is only meant to check whether the parent (client) has exited.

   The only code that might prematurely kill JDT-LS I could find is in https://github.com/eclipse/eclipse.jdt.ls/blob/3599212e7a7b8f0996bc970e532d94d9877e37e0/org.eclipse.jdt.ls.core/src/org/eclipse/jdt/ls/core/internal/handlers/JDTLanguageServer.java#L423 , or if some part of the workspace shutdown fails.

   ** Update ** : One of the solutions that was brought up is creating another (Java) application whose job is to detect such errors and if they match, notify the user how they can recover (eg. clean java LS workspace command). This is because JDT-LS clearly fails to launch in these cases. I guess the reason to create a service is to avoid doing too much work on the client-side (still would have to adopt the new app though). Fred Bricon (@fbricon) , Jinbo Wang (@testforstephen) , do I have this correct ?
