The CML Language Server server crashed 5 times
See original GitHub issueI am having problems getting the VS Code plugin to work:
- OS:
Darwin 20.4.0 Darwin Kernel Version 20.4.0 x86_64
- VSCode version:
1.56.0
- Context Mapper extenstion version:
v6.5.0
- Java version
"16.0.1" 2021-04-20 Java(TM) SE Runtime Environment (build 16.0.1+9-24)
- Graphviz version:
dot - graphviz version 2.47.1 (20210417.1919)
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:

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:
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)
