Only one workspace across multiple projects

[cutefish]

Hi,

Recently I noticed that only one workspace is opened for all my projects. I can see that I had different workspace before, and I am not sure when this issue starts. From the server log obtained with CocCommand java.open.serverLog. I got the following message:

!SESSION 2023-07-01 11:17:30.257 -----------------------------------------------
eclipse.buildId=unknown
java.version=20.0.1
java.vendor=Oracle Corporation
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_AU
Command-line arguments:  -data /home/xiaoy/.config/coc/extensions/coc-java-data/jdt_ws

That is, it is directing to the workspace directory jdt_ws which is the same for all my projects. I think previously I have seen other directories with project names appended after jdt_ws.

I don't think I did anything special. Here is my coc-settings.json

{
  "coc.preferences.formatOnSaveFiletypes": [
  ],

  "_java.trace.server" : "verbose",
  "java.import.gradle.enabled" : false,

  "java.format.settings.url" :
  "/scratch/baox/setup/nvim/codestyle-eclipse-java.xml",
  
  "java.compile.nullAnalysis.mode": "disabled",
  
  "list.nextKeymap" : "<C-n>",
  "list.previousKeymap" : "<C-p>",

  "list.maxHeight" : 20,
  "list.maxPreviewHeight" : 24,
  
  "java.completion.importOrder" : ["java", "javax", "oracle", "com.oracle", "com", "org"],

  "java.jdt.ls.vmargs" : "-Xmx2G",
}

What did I do wrong?

Perhaps I should give more context to my issue.

Recently I have been encountering the following error message whenever I open one of my projects.

The issue goes away if I clear the workspace with CocCommand java.clean.workspace. It seems there are two issues with the first being the server rejection and second the call stack size issue. I suspect that the server rejection is the cause and the call stack size issue is a secondary effect. Therefore, I checked the server log which shows an exception stack:

At the bottom of the stack is a complaint for a tree element not found where the name of the element is from another of my project. This leads me to suspect that the workspace are shared across all my projects.

Please let me know what I should do further to debug this issue. Thanks.

I also encountered similar problems.
Opening an unrelated file outside the project directory will also perform a Gradle sync.
