Assume the following class (comments and imports were stripped because they will not add to the understanding):

    public final class LogLevel extends Level
    {
	@SuppressWarnings( "hiding" )
	public final static Level ALL = Level.ALL;

	public final static Level AUDIT = new LogLevel( "AUDIT", 2000 );

	@SuppressWarnings( "hiding" )
	public final static Level CONFIG = Level.CONFIG;

	public final static Level DEBUG = new LogLevel( "DEBUG", Level.FINER.intValue() );

	public final static Level ENTRY = new LogLevel( "ENTRY", Level.FINEST.intValue() );

	public final static Level ERROR = new LogLevel( "ERROR", 1200 );

	public final static Level EXIT = new LogLevel( "EXIT", Level.FINEST.intValue() );

	@SuppressWarnings( "hiding" )
	public final static Level FINE = Level.FINE;

	@SuppressWarnings( "hiding" )
	public final static Level FINER = Level.FINER;

	@SuppressWarnings( "hiding" )
	public final static Level FINEST = Level.FINEST;

	@SuppressWarnings( "hiding" )
	public final static Level INFO = Level.INFO;

	public final static Level INIT = new LogLevel( "INIT", 850 );

	@SuppressWarnings( "hiding" )
	public final static Level OFF = Level.OFF;

	@SuppressWarnings( "hiding" )
	public final static Level SEVERE = Level.SEVERE;

	public final static Level SETUP = new LogLevel( "SETUP", 890 );

	public final static Level SHUTDOWN = new LogLevel( "SHUTDOWN", 890 );

	public final static Level TRACE = new LogLevel( "TRACE", Level.FINEST.intValue() );

	public final static Level VERBOSE = new LogLevel( "VERBOSE", Level.FINE.intValue() );

	@SuppressWarnings( "hiding" )
	public final static Level WARNING = Level.WARNING;

	private static final long serialVersionUID = -3872433371275614712L;

	private LogLevel( final String name, final int value )
	{
	    super( name, value, "ResBundle" );
	}
    }

The class add some new log levels to the JDK logging. It will also repeat the standard levels, as convenience: so I can statically import just LogLevel.* to have all log levels available at once.

The "copies" of the standard log levels (like SEVERE) will hide the "originals". In my original Eclipse settings, "hiding" should cause an error (Project|Properties - Java Compiler|Errors/Warnings - Name shadowing and conflicts - Field declaration hides another field or variable); in addition, I activated that @SuppressWarnings should suppress optional errors (Project|Properties - Java Compiler|Errors/Warnings - Annotations - Suppress optional errors with '@SuppressWarnings') and that errors should make the compiled code not executable (Project|Properties - Java Compiler|Errors/Warnings - Treat above errors like fatal compiler errors (make compiled code not executable)).

Everything works fine until I moved to Indigo SR1. From that time onwards, accessing one of the constants in LogLevel returned null. As you might imagine, it drove me crazy that a line like 

LogLevel.SEVERE.intValue()

caused a NullPointerException.

Obviously will "Suppress optional Errors" only suppress the error message and the generation of the compiling problem exception for an optional error, but the compiled code is still not executable - and this without any warning at generation time ...
