Try increasing memory of netbeans.

In the etc directory under your Netbeans-Home, edit the file netbeans.conf file. -Xms and -Xmx should be increased to the values that allow your program to compile.

Here are the instructions in netbeans.conf:

• Note that default -Xmx and -XX:MaxPermSize are selected for you automatically. You can find these values in var/log/messages.log file in your userdir. The automatically selected value can be overridden by specifying -J-Xmx or -J-XX:MaxPermSize= here or on the command line.

Put the values in the netbeans_default_options string.
