java - Jar not visible, but javaw.exe is running -

-

on 1 of windows systems, have problem running jar file.

when double click on jar file, first jframe (splash screen) appears , hides again,but main jframe doesn't become visible ... when monitoring services, noticed javaw.exe keeps running ...

when launching jar command prompt (java -jar c:\myjar.jar), works fine ...

i've tried creating output file while running jar, , file created, remains empty (java -jar c:\myjar.jar > d:\output.txt)

does have idea problem ?

java application close (javaw.exe close) after of threads finishes work. disposing thread used produce jframe, other threads still running (and waiting something).

i can not further without more inforamtion specific application (e.g. code)
