[KUGDev]

The plugin to test the behaviour: https://github.com/zowe/zowe-cobol-language-support-intellij There is demo.cbl file to test the issue when the plugin is installed. Tested with LSP4IJ 0.0.2

The issue appears during the plug-in run in development mode

I don't see any com.redhat.*stacktrace, have you the same problem with another language (like Java) which is not associated to a language server?

I noticed this problem when we use file index to retrieve a file from String uri that I have fixed since last version of IJ (2024.2 I think)

I wonder if it is a bug from IJ?

Current stable is 2024.1 The same issue is reproducible for other LSP servers as well Not sure if it is the plug-in's problem, but I saw some usages of this feature inside of the LSP4IJ's code, so created the issue in here as the most specific place to make a heads-up or get some clarification

[angelozerr]

If you do Find Usages for Java code for instance, do you see this issue?

[KUGDev]

It looks like the other code causes the same issue, so most probably this is the IntelliJ's problem

[angelozerr]

Thanks for your feedback, I think we can close this issue since it is a JetBrains issue, right?

[KUGDev]

Ok @angelozerr, if you think so, we can close the issue But the thing is that this issues is not reproducible with other plugins It does not bother me until I call the Find Usages feature, so I will be avoiding it then Thank you

[angelozerr]

My main problem with your issue is that I dont see any stack trace from LSP4IJ so it will hard to fix something from LSP4IJ
