The simplest possible solution here would be to increase your permagen space (which is different from your regular heap). In the case of Eclipse, it implies changing your eclipse.ini file which lies in the Eclipse root directory by adding:
--launcher.XXMaxPermSize
256m
A lot of Eclipse users seem to have the same problem so reading the posts there might help your cause in case the above suggestion doesn't solve it.
