Test Projects Helios 3.6.1

Basic Setup: 

A Headless RCP Application with the following dependencies:
- org.elcipse.core.runtime
- javax.persistence
- org.eclipse.persistence.jpa
- (jdbc connector - in my testcase a mysqlWrapper)

Target Platform including:
- RCP Target Components
- EclipseLink Target Components


The Effect:

Create a new Run Configuration (Eclipse Application). 
On the Plug-ins Tab:
- Set "Launch with" to "plug-ins selected below only"
- Press "Deselect All"
- Select the Application Project Plug-in (i.e. "de.kware.testjpa")
- Set to false "Include optional dependencies ..."
- Choose "Add Required Plug-ins"

A) The plugin org.eclipse.persistence.antlr is not added to the configuration (Eclipse Application) on "Add Required Plug-ins" when "Include optional dependencies ..." is not activated.

B) After adding the plugin manualy to the configuration it still doesn't work. The classloader will bring a ClassNotFoundException for org.eclipse.persistence.internal.libraries.antlr.runtime.Parser.

C) After fooling around a bit I noticed that after changing the order of the dependencies in the Plug-in Editor, it will suddenly work.


Why is this a Problem:

Without org.eclipse.persistence.antlr the creation of a TypedQuery results in a ClassNotFoundException for org.eclipse.persistence.internal.libraries.antlr.runtime.Parser.
