Sunitha Kambhampati commented on DERBY-1867:

With IBM 1.4.1 JVM, trying to connect to the server using the derby client with security mechanism
8 (USRSSSBPWD) will result in error 

Connecting using the client driver with security mechanism 8 will throw the following error
ERROR XJ112: Security exception encountered, see next exception for details.
The stack trace will show that the problem is caused by java.security.NoSuchAlgorithmException:
SHA1PRNG SecureRandom not available

Current USRSSBPWD implementation uses SHA1PRNG algorithm to generate random number(seed) that
gets exchanged between client and the server. The SHA1PRNG algorithm is not available with
the JCE provider that comes with IBM JVM version 1.4.1.

If you need to use the security mechanism 8, then make sure that support for SHA1PRNG is available
in the JCE provider that is available with a particular JVM.
For e.g. Use IBM 1.4.2 JVM that has support for SHA1PRNG or the Sun JVMs.
