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.

for (int i= 0; i < fButtonLabels.length; i++) {
					String currLabel= fButtonLabels[i];
					if (currLabel != null) {
						fButtonControls[i]= createButton(contents, currLabel, listener);
						fButtonControls[i].setEnabled(isEnabled() && fButtonsEnabled[i]);
					} else {
						fButtonControls[i]= null;
						createSeparator(contents);
					}
				}
			}
			fLastSeparator= createSeparator(contents);
			updateButtonState();
			fButtonsControl= contents;
		}
		return fButtonsControl;
	}
	private void doButtonSelected(SelectionEvent e) {
		if (fButtonControls != null) {
			for (int i= 0; i < fButtonControls.length; i++) {
				if (e.widget == fButtonControls[i]) {
					buttonPressed(i);
					return;
				}
			}
		}
	}
