This error occurs when the JVM runs out of space in the permanent generation heap. Since the defaults for the JVM are quite low, the first step should be to increase the default using -XX:MaxPermSize.
You can go to the Debug or Run Configurations of Eclipse and there in the Argument tab, under VM Arguments you can replace the existing aruments by
-Xms40m -Xmx384m -XX:MaxPermSize=128M
If the problem still persists, you can use :
-XX:MaxPermSize=256M or -XX:MaxPermSize=512M instead of -XX:MaxPermSize=128M

Try this Code
-Xms768m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=256m
or
-Xms768m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m
You can either do this through Run/Debug configurations or you can go to the eclipse.ini file in the directory where your eclipse is installed and you can add the following under -vmargs :-
-Xms768m
-Xmx1024m
-XX:PermSize=256m
-XX:MaxPermSize=256m
It should work.

Uh, no. I believe anything in eclipse.ini is for Eclipse itself and not
for the applications you're running. You were right the first time: do
that in the Run/Debug configuration.
