Troubleshooting
Notification message: The Language Support for Apache Camel server crashed 5 times in the last 3 minutes. The server will not be restarted.
Have a look to View -> Output -> Language Support for Apache Camel
If the log contains:
[Info - 1:34:41 PM] Connection to server got closed. Server will restart.
Exception in thread "main" java.lang.UnsupportedClassVersionError: com/github/cameltooling/lsp/internal/Runner has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
it means that a too old version is used. In this specific case, Java 8 although Java 11+ is required. Either configure your system to have Java 11+ or modify java.home VS Code preference settings to point to a Java 11+ installation.
It is possible to activate logs for communication between Language Server and VS Code client. In command palette, call Preferences: Open Settings (JSON) and provide "LANGUAGE_ID_APACHE_CAMEL.trace.server": "verbose".
Depending on which languages used, it can be interesting to activate some others traces:
"yaml.trace.server": "verbose""xml.trace.server": "verbose""java.trace.server": "messages"
