Increasing Memory Settings (applicable to all builds)

The default memory settings for NetBeans should be increased for UML projects. If you have the available memory,

1. Locate your NetBeans installation directory ($install_dir). This can be found by starting up NetBeans and selecting Help -> About then select the Detail tab.
2. Edit the $install_dir/etc/netbeans.conf file.
3. Find the line defining netbeans_default_options.
4. Increase the maximum memory attribute to -J-Xmx512m.
5. If you experience heap overflows while working with larger files, you should increase this value further.
