OCLinEcore : PermGen space error [message #989292]

Hi,

I have created a very simple ecore model (see below) to which I have added a constraint using OCLinEcore.

package ControlModel : control = '<URI>'
{
class Node
{
attribute Description : String[?] = '' { ordered };
invariant DescCheck: Description <> null and Description.size() > 5;
}
}

If I create a dynamic instance of 'Node', all is well and the validation will correctly report null or Description <= 5.

If I create a generator model, generate all code and run the resultant editor (as an eclipse application), on attempting to validate, I receive the following error, and the validation hangs:

Exception in thread "ModalContext" java.lang.OutOfMemoryError: PermGen space
java.lang.OutOfMemoryError: PermGen space
java.lang.OutOfMemoryError: PermGen space
java.lang.OutOfMemoryError: PermGen space
java.lang.OutOfMemoryError: PermGen space
......

I am using Eclipse Juno SR1 on Windows 7 64 bit.

Any pointers would be really appreciated.

Regards

Dan

All,

Problem as PermGen space (I guess the answer was in the error message!!). Implemented suggestion as per http://www.eclipse.org/forums/index.php/m/898737/

Now validation works as expected.

Hi

Well solved. There is at least one Bugzilla open bemoaning the failure
of Eclipse to ship a solution to the JVM inadequacy. Most modeling
projects have this guaranteed failure for new users.
