Bug: yEd (3.18.2, 3.19) freezes regularly for 10-20 seconds (Linux, different JVMs)

0 votes

I'm using yEd for Linux and get regular UI freezes for 10-20 seconds.

The system becomes completely unresponsive for that time, but than it gets back to usable state. Freezing occurs again and again during the same yEd working session.

Switching to different JVMs doesn't solve the issue.

The workaround which works for me is to run yEd for Windows in the VisualVM virtual machine, on the same hardware where Linux runs. In that case freezing never occurs.


Linux Mint 18.3 Sylvia

$ cat /proc/version
Linux version 4.15.0-47-generic (buildd@lgw01-amd64-028) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10)) #50~16.04.1-Ubuntu SMP Fri Mar 15 16:06:21 UTC 2019


1) built-in Java 8 for yEd 3.18.2

Thank you very much for error report. However, the fact that the freeze never occurs on Windows means that this is not an error in the yEd code base (which is identical for Windows and Linux) but a problem in the Java code base.
I am using yEd on Ubuntu 16.04 and there are never freezes. I suspect that the problem is actually related to Java on Linux Mint. Unfortunately, this means there is not much we can do but hoping for Oracle to fix the problem in a future Java version.
