openJDK Platform binary process runs forever

[kozyakin]

Describe the bug
After executing ltex-cli.bat on any tex-file the process openJDK Platform binary (=java.exe), which occupies about 800 MB, remains in RAM of Windows 10.

Steps to reproduce

1. Run the command

ltex-cli.bat <tex file name>

2. After finishing this command, inspect the running processes by Task Manager
3. Will be seen that the process openJDK Platform binary, which occupies about 800 MB, still running in background.

Expected behavior
The process openJDK Platform binary (=java.exe) should be stopped after executing ltex-cli.bat <tex file name>

LTeX configuration
Default

Version information

• Operating system: Windows 10 21H1
• ltex-ls: 15.0.0
• Java: Microsoft openJDK 17

Additional context/information
The problem may be solved by manual "killing" java, say, by insetring in the end of ltex-cli.bat the string

taskkill /f /im java.exe > nul

but this is definitely not the good solution since this string kills ALL the instances of running java.exe.

I can't reproduce this. As far as I understand, ltex-cli.bat finishes (i.e., the cmd prompt C:\...> is displayed again), but java.exe continues to run. I don't see any Java processes on my system after running ltex-cli.bat.

Can you please open a second cmd window and run wmic process where "name like 'java.exe'" get processid,commandline three times:

• once before the execution of ltex-cli.bat,
• once during the execution of ltex-cli.bat (cmd prompt is not yet visible),
• once after the execution of ltex-cli.bat (cmd prompt is visible again),

and post the three outputs?

Please find attached files "before", "during" and "after" of outputs of the command wmic process where "name like '%java%'" which you requested (before execution, during and after).

I also attached related screenshots of Task Manage

Thanks for the info. Looks like the Java process for ltex-ls is not properly terminated by the Java process for lsp-cli.

I still can't reproduce this, even on another machine, and with the Microsoft build of OpenJDK. But I made lsp-cli terminate ltex-ls more aggressively, see commits above. Can you please test the pre-release 15.0.1-alpha.2 to see if the issue is resolved there (see docs on testing pre-releases)?

[kozyakin]

Now, all is running as expected: no openJDK Platform binary process after ltex-cli.bat finished!

Well done! Great! Thanks a lot!

This issue is now fixed on develop. The fix will be included in the next release of LT_EX.

If you don't want to wait, you can try out the nightly pre-release tomorrow. Nightly pre-releases are published every morning at around 4am UTC.
