Caot launch "Icedtea Web Control Panel" in Ubuntu Studio 16.04.

Hi,

I have just installed "Icedtea Web Control Panel" in Ubuntu Studio 16.04 through "Software".
However, I get the error message "Failed to execute child process /usr/bin/itweb-setting".

Please note that my java version is 1.8.0_91

$ java -showversion
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-0ubuntu4~16.04.1-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

I hope someone can help.
