Bug 62086 [User library] Jars in User Libraries Can't be ordered
Inorder to get a patch to Easymock to work the patch jar must be first in the classpath. There does not appear to be a way to do this with the User Libraries. I'm using the I20040506 build.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/dialogfields/TreeListDialogField.java
boolean enabled= isEnabled();
		if (isOkToUse(fTreeControl)) {
			if (!enabled) {
				fSelectionWhenEnabled= fTree.getSelection();
				selectElements(null);
			} else {
				selectElements(fSelectionWhenEnabled);
				fSelectionWhenEnabled= null;
			}
			fTreeControl.setEnabled(enabled);
		}
		updateButtonState();
	}
	/**
	* Sets a button enabled or disabled.
	*/
	public void enableButton(int index, boolean enable) {
		if (fButtonsEnabled != null && index < fButtonsEnabled.length) {
			fButtonsEnabled[index]= enable;
			updateButtonState();
		}
	}
	private boolean isButtonEnabled(ISelection sel, int index) {
		boolean extraState= getManagedButtonState(sel, index);
		return isEnabled() && extraState && fButtonsEnabled[index];
	}
	
	/**
	* Sets the elements shown in the list.
