Beginning Cryptography with Java Review by reviewer
Very hands-on
Whether it is complete or not (of course, it is not), I would challenge anyone to point at a single alternative book covering Java cryptography at a greater level of details. The style is clear, coverage of ASN.1 is very helpful, and selection of BouncyCastle open source cryptoprovider is the most natural one. Lots more of details and code samples can be found in Bouncy Castle javadocs, but to navigate them without conceptual understanding of Java security in general and BouncyCastle implementation in particular, gained from the book like this one, would be a nightmare.
"Inside Java 2 Platform Security: Architecture, API Design, and Implementation (2nd Edition)" would be another book to recommend, for general overview of Java Security Platform, and, also, to make sense of Java Cryptography Extension (JCE) APIs standardizing access to cryptoproviders' (such as BouncyCastle) libraries. But, of course, the two books have very little overlap.
