keytool (1.5) has imported my pem certificates just fine. I converted
a public/private pem keypair I had (cat'd in one file), which
converted, then I imported it into a jks file with keytool. It
imported as a trustedCertEntry, which is what cert-only certs and CA
certs get imported as. So, I tried converting just my private key to
DER from PEM, and got an error. It looks like private keys just can't
be changed from one form to another. There seems to be a black hole
of knowledge about this -- I haven't found docs on how to do it, and
haven't seen any notes that it is impossible. Weird.

The private key has the regular -----BEGIN RSA PRIVATE KEY----- and
-----END RSA PRIVATE KEY----- lines. It is not encrypted.
