Bug 78901 Restore defaults does not work on Java > Compiler preference page [preferences] [compiler]
I200411170800. I want to go back to default compiler settings, but the "Restore Defaults" button doesn't appear to do anything.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/CompilerPreferencePage.java
/*
	 * @see org.eclipse.jface.preference.IPreferencePage#performDefaults()
	 */
	protected void performDefaults() {
		super.performDefaults();
		if (fConfigurationBlock != null && useProjectSettings()) {
			fConfigurationBlock.performDefaults();
		}
	}
	/*
	 * @see org.eclipse.jface.preference.IPreferencePage#performOk()
	 */
	public boolean performOk() {
		if (fConfigurationBlock != null && !fConfigurationBlock.performOk(useProjectSettings())) {
			return false;
		}	
		return super.performOk();
	}
	
	/* (non-Javadoc)
	 * @see org.eclipse.jdt.internal.ui.preferences.PropertyAndPreferencePage#setElement(org.eclipse.core.runtime.IAdaptable)

	public void setElement(IAdaptable element) {
		super.setElement(element);
		setDescription(null); 
	}
