Ronny Perinke commented on NETBEANS-5740:
------------------------------------------
I was able to "reproduce" it by opening a multi-module Java Maven project and
pasting a few lines of code into one of the the classes from a sub-module. The
project has a Java compile level of 16. It uses compile on save with nb-javac
enabled and lombok 18.20. A dump file for the class is created in
{{<profile>/var/log}}. Sometimes Netbeans freezes immediately when pasting the
code (_it is not even showing up in the editor_) and sometimes it requires a
few undo/redo steps to cause a freeze.
messages.log did not contain the lines about java.util.zip.CRC32C as mentioned
above by Diego.

> Netbeans 12.4 randomly freezes
> ------------------------------
>
> Key: NETBEANS-5740
> URL: https://issues.apache.org/jira/browse/NETBEANS-5740
> Project: NetBeans
> Issue Type: Bug
> Affects Versions: 12.4
> Environment: Ubuntu 20.04
> Netbeans 12.4
> OpenJDK 11.0.11
> Reporter: Diego Díez
> Priority: Major
>
> We have started experiencing random freezes after upgrading to Netbeans 12.3,
> not responding any component to mouse or keyboard interactions.
> We have also noticed that lombok-1.18.18 stopped working with the newer
> nb-javac installed with the 12.4 version (java16 support). I can't confirm
> whether this is related with the freezes or not. Using lombok-1.18.20 seems
> to work well, though.
> Any ideas? Is there any log to look for errors?
> As a workaround we have downgraded to 12.3 as it is a blocking issue for us,
> being forced to kill the process every time it gets stuck.
