SQL Developer

If you have difficulties with running SQL Developer (in my case 4.0.2.15.21) from Oracle in console on Linux you can see such stack trace :

# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007feb22ed8be0, pid=32116, tid=140649711318784
#
# JRE version: Java(TM) SE Runtime Environment (7.0_65-b17) (build 1.7.0_65-b17)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (24.65-b04 mixed mode linux-amd64 compressed oops)
# Problematic frame:
# C  0x00007feb22ed8be0
#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

/home/lukasz/sqldeveloper/sqldeveloper/bin/../../ide/bin/launcher.sh: line 1193: 32116 Przerwane               (core dumped) ${JAVA} "${APP_VM_OPTS[@]}" ${APP_ENV_VARS} -classpath ${APP_CLASSPATH} ${APP_MAIN_CLASS} "${APP_APP_OPTS[@]}"

So, fix of this problem is quite easy - go to file sqldeveloper.sh which is located in folder of your SQL Developer and add at the beginning of this file the following line :
unset GNOME_DESKTOP_SESSION_ID

SQLDeveloper.sh
