In the "Appendix B: SunJCE Default Keysizes" of JCE reference guide, it still has
o Blowfish: 56 bits
which is the default value for pre-1.4.2 releases.
Starting 1.4.2, the default value for Blowfish has been lifted up to 128 bits (see 4526256), so the JCE reference guide should be updated as well.
