You probably get these warnings because of --disable-shared. Security
providers are loaded dynamically, based on a configuration file, and in
a statically linked system that might fail (though, I don't know why it
should; I would assume that those symbols would be linked in).

However, even if the dynamic loading fails, we initialize our providers
with our default set. You can confirm that these providers are loaded by
calling Security.getProviders, and listing them.

We don't implement PBEWithMD5AndDES in Classpath or libgcj. So
regardless of whether or not static linking is causing issues, this
program will still throw this exception.

(I get the same exception on jamvm, with Classpath HEAD, minus the
warnings).

Do you have a pointer to a description of the PBEWithMD5AndDES
algorithm? It's probably pretty easy to write, because the building
blocks are all there.

Cheers.
