Additional context previous version (it's overridden by 2.1.2, so i couldn't get) visualvm was working w/ that l&f option.

Please attach whole messages.log file. Thanks.

umjammer commented 2 years ago

here it is.

visualvm-log.zip

it's located at ~/Library/Application Support/VisualVM/2.1.2/var/log is it documented?

and i found previous version is 2.1.1, because there is the directory named that version.

A quick tip - have you tried the VisualVM --laf argument to set the LaF instead of -J-Dswing.defaultlaf?

Please see https://visualvm.github.io/docs/command-line-options.html#appearance_options and the example right above this section, for --cp:p and --cp:a.

umjammer commented 2 years ago

it works!

i just remembered user configuration file is located at ~/Library/Application Support/VisualVM/x.x.x/etc visualvm.conf for 1.2.1 is still there... i used --laf and --cp:a for 1.2.1 ...

sorry about the fuss
