I am working with a Java program (reading large files) on Eclipse - Windows. After running my program I get the error:

Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded

I see on http://www.oracle.com/technetwork/java/javase/gc-tuning-6-140523.html#par_gc.oom that I should add the option -XX:-UseGCOverheadLimit to the command line.

Where should I add this option? How can I solve this?

In your Tomcat bin folder you will find a file Catalina.sh which has a variable called CATALINA_OPTS. You need set it with -XX:-UseGCOverheadLimit.

Though I am not very learned in this subject, AFAIK this is a temporary solution. You make check this answer. It might help.
