Even superstar hackers introduce the occasional bug.

Mr. Bloch is listed as the author of java.util.EnumMap. The clone() method doesn't reset the entrySet member. So changes to the original will seemingly affect the clone.

I filed a bug report on this long ago but no luck. This bug has been present in every JDK release since 1.5.

It's open source now, so you can go ahead and submit a patch to the core-libs-dev@openjdk.java.net mailing list.

Is the 1st edition a very good book? I've heard about it but never checked it out.

My current favorite is Head First Java. I've successfully helped 2 non-hackers to learn Java with it. The casual (even comic) writing style is really easy to read.

It's a geat book. Required reading if you're coding Java. Google gives it out to new employees.

Joshua Bloch writes well and is more qualified that most to write a book on Java. His little stories that he weaves in about this part or that of the standard library being broken are pretty sweet.

Head First Java is a good book for beginners. If you want to increase your Java knowledge (especially in designing framework/library), this is the book to read.

Of course, this, and other books that specifically talk about JVM.
