Bluej not running

Release 4.4 64-bit
Kernel Linux 4.18.0-parrot10-amd64 x86_64
MATE 1.20.3

Debian standard

multi boot:- yes

bluej 4.1.4/4.1.3 installed sucessfully but not running nither before restarting the system or after. I also tried re-installing bluej but didnt work.

If you start it from the command line, what does it output?.

dosnt work though

finally solved it by installing “Oracle jdk 8” and making it default instead of “Open jdk 8”.
