A DESCRIPTION OF THE PROBLEM :
Bug #1:

Bug Name: JVM crashes on exit

Comments From Christian:
------------------------
Each time the IDE is closed, a dialog box with the following content is displayed (as if the JVM crashed):

JVM terminated. Exit code=255

This might be related to calling System.exit which is not a good way to close a Java application.
I think it is better to investigate what is blocking JVM in the first place (most likely it is blocked by reading AMPL input from a pipe) and fix it instead of using
System.exit which can have potentially dangerous side-effects in addition to annoying dialogs.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
not cause an issue while exit the application
ACTUAL -
close the application when press EXIT

ERROR MESSAGES/STACK TRACES THAT OCCUR :
JVM terminated. Exit code=255
