Sample extension to reproduce the issue

Using the folder picker from a Java extension causes LibreOffice to hang when
using the gtk3_kde5 VCL plugin.

Steps to reproduce:

0) use KDE Plasma
1) install the attached demo extension
2) start LibreOffice Writer with the gtk3_kde5 VCL plugin:
   SAL_USE_VCLPLUGIN=gtk3_kde5 libreoffice --writer
3) click the "Test Extension" -> "Save (new)" menu item
   -> a native Qt folder picker appears
4) select any directory and click "OK"

Result: LibreOffice hangs

using e.g. LibreOffice from Debian testing:

Version: 6.1.5.2
Build ID: 1:6.1.5-2
CPU threads: 4; OS: Linux 4.19; UI render: default; VCL: gtk3_kde5; 
Locale: en-GB (en_GB.UTF-8); Calc: group threaded</pre>
