This property sets the Java system properties for the Java application being launched. These are entered as follows:
propName=propValue
The "=" is parsed out and replaced by the appropriate separator specific to the
JVM being used for the application. Additionally, the appropriate
command line option required by that JVM is automatically included in the
launch command.
If you need multiple system properties, press Enter at the end of
each line in the property editor and add one property per line. They
will display with a comma separator in the IDE property table.
