Description Amigo CLA 2011-08-21 07:45:46 EDT 
Build Identifier: I20110613-1736

PDT build ID - 3.0.0.v20110516-1100-77--84_23JBVgSVXO7XGJz0VLa9O

In a file that consists of thousands rows CA (or Validator) it occurs error - "Unhandled event loop exception" with exception trace:

java.lang.StackOverflowError
	at org.eclipse.core.internal.resources.Resource.hashCode(Resource.java:1287)
	at org.eclipse.dltk.internal.core.ProjectFragment.hashCode(ProjectFragment.java:114)

	at org.eclipse.dltk.internal.core.hierarchy.TypeHierarchy.getAllSuperclasses(TypeHierarchy.java:483)
...

If I try force CA by Ctrl+Space it show window without completion (but it must be). 

In small files it works ok.

Reproducible: Sometimes

Steps to Reproduce:
1. Occurs for big PHP files (I've got more than 5000 rows)
Comment 1 Amigo CLA 2011-08-21 09:00:58 EDT 
If I disable validation there is no exception. But there is no CA too.
Comment 2 Roy Ganor CLA 2011-08-21 09:09:43 EDT

Thanks

example

Here is PHP-files for example
------
Also I've founded that it occurs after typing something after keyword $this->... inside a method.
CA works fine with keyword parent::

I've tested my project at Linux (x86-64)
Build ID - 20110615-0604
PDT Build ID - 3.0.0 v20110516-1100
Java 1.7.0-b147
Works fine
I wonder. It seems like virtual machine for windows generates this exception at a low level...

Additional searching...

I think something wrong with multiply extending classes.

--------------- Works
	require_once($_SERVER['DOCUMENT_ROOT'] . "/modules/core/class/DOM.php");
	class B  extends _Element  {
		public function m() {
			$this->
		}
	}
---------------


--------------- Occurs error
	require_once($_SERVER['DOCUMENT_ROOT'] . "/modules/core/class/DOM.php");
	class B  extends _HTMLElement  {
		public function m() {
			$this->
		}
	}
---------------

typing something after "$this->" generates exception
