jdeveloper 12c (12.1.3) is crashing on ubuntu 15.04 with unity

Jdeveloper 12c and especially version 12.1.3 is crashing when used with unity on Ubuntu 15.04. The problem is JAyatana a package for integrate swing applications with unity that is installed by default in 15.04.

A quick solution if you don't have other java swing applications is to remove JAyatana.

$ sudo apt-get remove jayatana

A better solution is to create a script to open jdeveloper and unset JAVA_TOOL_OPTIONS that JAyatana globally sets and open jdeveloper using that script.

#!/bin/bash
export JDEV_USER_HOME=$HOME/workspace
unset JAVA_TOOLS_OPTIONS
$HOME/Oracle/fmw12c/jdeveloper/jdev/bin/jdev > /dev/null 2>1 &
