Created attachment 4040
runnable jar with source
This java program runs normally on gnome, mac os, while on xfce, the modal dialog can't get focus when opened more than once.
The attachment is a jar with source code for you to verify the bug.
We want a frameless window, which need open a modal dialog. As a result, we have to use JFrame::setUndecorated(true) to remove the window decoration, and the problems occurs, so we think this is somethine different between xfce's window manager and other desktop's.
Can you please check this problem?
This problem has been tested on xubuntu as well as another linux distribution we maintained by ourselves, both based on xfce 4.8.
Works fine here.
Have you checked against the latest xfwm4-4.8.3 released a couple of days ago?
It contains a fix or Java apps that looks a lot like your issue.
Thank you. I'll try the latest version and give the result.

Working fine here, Xfce 4.12 & Xfwm4 4.12.3.
Reopen if it somehow still affects you.
