Stm32CubeIDE crashes on startup: "Java" is not responding

[BRobe.1641]

My linux laptop (Ubuntu 22.04) failed to properly 'sleep' overnight - there is something wrong with the install of Ubuntu on my laptop. At the time, CubeIDE 1.11.2 was running, with Devstyle plugin (which has itself caused problems for me in the past). I have tried removing the 'st' folder in /opt, and reinstalling, and that had no impact. While this may just be a problem with my system76 linux laptop, other applications appear to be functioning normally.

To clarify, when I load STM32CubeIDE, the devstyle splash screen came up, and then after I proceed into the IDE, it freezes, with a message that says "Java" is not responding. On starting up since, I have skipped the devstyle splash screen, and instead get the blue-colored splash of CubeIDE - but it just freezes, saying the same thing, and suggesting I force quit.

Is there a way to diagnose this problem?

Hello @BRobe.1641​ 

First let me thank you for posting.

Could you share the .log file found under the workspace_name\.metadata.

Thanks,

Semer.

I'm sorry for not responding - I did not see that there was a response. I ended up wiping ubuntu altogether, reinstalling, and then reinstalling Cube IDE. Then the laptop powered down in a similar way to that described above, and I now cannot load the IDE at all. Here is the .log file:

Also, I think I found where the executable for STM32CubeIDE is installed (/opt/st/stm32cubeide_1.11.2), but when I execute it from the command line, i.e.:

/opt/st/stm32cubeide_1.11.2$ ./stm32cubeide

I get an error, as follows:

Please choose another workspace, as [workspace folder location] is currently in use. RETRY/CHOOSE

Is it possible that my laptop powered down improperly, while I had left STM32Cube running, and so it is causing this error?

[HackyJ]

Have the same issue after closing the laptop before ending the stm32cubeide_1.12 finally.

at startup this morning, even after a restart of linux, the ide locks up with java did not answer.

I the started a second instance of stm32cubeide which requested a new workspace.

With this workspace it works. Seems something in the workspace gets damaged on hibernate.

[HackyJ]

Added the damaged workspace for analysis.

Hello, I had this problem, where my IDE wouldnt open, and give the "java not responding" error after about 2 minutes of waiting. I was able to open the IDE again by deleting the .metadata folder in my workspace. Everything seems to be working now, I just needed to open the workspace directory again. Some configurations seem to have reverted back.

I hope this helps

[IAnan.3]

I have the same problem. But the difference is that I use ubuntu 23.04.

[shane mattner]

I ran into this same problem today running Fedora 38 on a Thinkpad Carbon X1.  I was able to start CubeIDE only if the workspace was pointed toward the default location.  For me that workspace path is /home/shane/STM32CubeIDE/workspace_1.12.1

After changing the workspace path I was able to create new projects, build, and debug as normal.

Update: I ran into this problem again on Ubuntu 22.04 and v1.12.1 of CubeIDE.  I removed `/opt/st/stm32cubeide_1.12.1/` and installed v1.13.1.  Cube is working now.

Removing the .metadata directory works for me.   I am running on Ubuntu 22.x Desktop with the STM32CubeIDE v 1.144.0.   Additionally, I am running this on a Proxmox virtual machine with a virtual USB port mapped to a physical port.
