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/buildpaths/SourceAttachmentBlock.java
if (field == fFileNameField) {
			IPath jarFilePath= isVariableEntry() ? chooseExtension() : chooseExtJarFile();
			if (jarFilePath != null) {
				fFileNameField.setText(jarFilePath.toString());
			}
		}	
	}
	
	
	private void attachmentDialogFieldChanged(DialogField field) {
		if (field == fFileNameField) {
			fNameStatus= updateFileNameStatus();
		} else if (field == fWorkspaceButton) {
			IPath jarFilePath= chooseInternal();
			if (jarFilePath != null) {
				fFileNameField.setText(jarFilePath.toString());
			}
			return;
		} else if (field == fExternalFolderButton) {
			IPath folderPath= chooseExtFolder();
			if (folderPath != null) {
				fFileNameField.setText(folderPath.toString());
			}
			return;
		}
		doStatusLineUpdate();
	}	
		
	private void doStatusLineUpdate() {
		fFileNameField.enableButton(canBrowseFileName());
