2.1 M3 I am missing an option to disable the compiler warning upon assigning a variable to itself...
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/CompilerConfigurationBlock.java
label= JavaUIMessages.getString("CompilerConfigurationBlock.pb_assert_as_identifier.label"); 
		addComboBox(complianceComposite, label, PREF_PB_ASSERT_AS_IDENTIFIER, errorWarningIgnore, errorWarningIgnoreLabels, indent);		
		Control[] allChildren= complianceComposite.getChildren();
		fComplianceControls.addAll(Arrays.asList(allChildren));
		fComplianceControls.removeAll(Arrays.asList(otherChildren));
		
		return complianceComposite;
	}
		
	private void addCheckBox(Composite parent, String label, String key, String[] values, int indent) {
		ControlData data= new ControlData(key, values);
		
		GridData gd= new GridData(GridData.HORIZONTAL_ALIGN_FILL);
		gd.horizontalSpan= 2;
		gd.horizontalIndent= indent;
		
		Button checkBox= new Button(parent, SWT.CHECK);
		checkBox.setText(label);
		checkBox.setData(data);
		checkBox.setLayoutData(gd);
		checkBox.addSelectionListener(fSelectionListener);
		
		String currValue= (String)fWorkingValues.get(key);	
		checkBox.setSelection(data.getSelection(currValue) == 0);
		
		fCheckBoxes.add(checkBox);
	}
