I want to double click on a executable jar file to start it.
the jar file is marked executable:

$ ll
insgesamt 28
-rwxrwxr-x. 1 thomas thomas  3759 21. Apr 16:22 podsync.jar

I registered an binary format handler via systemd:

$ cat /etc/binfmt.d/java.conf 
# binfmt_misc support for executable Jar files:
:ExecutableJAR:E::jar::/usr/bin/jarwrapper:

in bash I can enter:
$ ./podsync.jar

and the program starts.

But in Thunar I cannot double click to start the program/jar file.

How to achive this?
