#15 Algorithm DH not available

[David Rabinowitz]

I've downloaded the last version (0.1.20) and compiled
it vs JDK 1.4.2_06. When running the exec example I got
the following error
java.security.NoSuchAlgorithmException: Algorithm DH
not available
java.lang.NullPointerException

Digging in the mailing list didn't help.
