The CML Language Server server crashed 5 times #290

Closed oweidner closed 1 year ago

oweidner commented 3 years ago

I am having problems getting the VS Code plugin to work:

The error message I get is The CML Language Server server crashed 5 times in the last 3 minutes. The server will not be restarted.

The console output looks like this:

[Info  - 10:13:27 AM] Connection to server got closed. Server will restart.
oweidner commented 3 years ago

It seems that this issue is specific to Orcale's JDK. With OpenJDK the extension / language server launches just fine. However, I still see a warning hinting at a similar problem:

WARNING: An illegal reflective access operation has occurred

Thanks for reporting this issue @oweidner; good to know that this is a problem with Oracle's JDK. I'm aware of the warning you mentioned above. Unfortunately, this is a problem in the Xtext framework. I don't know if the @xtext guys already fixed this in a newer version; but I will check.

I am having same problem but with OpenJDK. VS Code info:

java -version
openjdk version "16.0.1" 2021-04-20

therealjawss commented 2 years ago

Also the same with version 16 openjdk version "17" 2021-09-14 OpenJDK Runtime Environment (build 17+35-2724) OpenJDK 64-Bit Server VM (build 17+35-2724, mixed mode, sharing)

update: finally got it working by installing just version 15 openjdk 15 2020-09-15 OpenJDK Runtime Environment (build 15+36-1562) OpenJDK 64-Bit Server VM (build 15+36-1562, mixed mode, sharing)

For those who does not want install JDK 15 to run this extension, I found workaround for JDK 16 using infromation from here https://stackoverflow.com/questions/41265266/how-to-solve-inaccessibleobjectexception-unable-to-make-member-accessible-m What I did was changing how vs-code extension starts in %USERPROFILE%.vscode\extensions\contextmapper.context-mapper-vscode-extension-6.5.2\lsp\bin\context-mapper-lsp.bat by adding --add-opens java.base/java.lang=ALL-UNNAMED:

@rem Execute context-mapper-lsp
"%JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% %CONTEXT_MAPPER_LSP_OPTS% --add-opens java.base/java.lang=ALL-UNNAMED -classpath "%CLASSPATH%" org.eclipse.xtext.ide.server.ServerLauncher %CMD_LINE_ARGS%
vancluever commented 2 years ago

Note that you can also export the --add-opens java.base/java.lang=ALL-UNNAMED flag to CONTEXT_MAPPER_LSP_OPTS in your respective environment to avoid having to edit files the extension that may be reverted at a later date.

Just hit the same issue on Windows and also on Mac. The workaround from @evgeniykim does not help in my case. Is there any other known workaround?

stefan-ka commented 1 year ago

Hi @oweidner, @karimElJed, @vancluever, @evgeniykim, @therealjawss Today we released v6.7.0 of Context Mapper that finally supports Java 17: https://contextmapper.org/news/2022/12/02/v6.7.0-released/ From my perspective this issue should be solved, so I'll close it. If you still experience issues, feel free to re-open or create other issues. Best regards, Stefan
