  700                         "Algorithm constraints check failed on 
keysize limits."
  701                                 + algorithm + " " + size + "bit 
used with " +

Looks like you could insert a couple of spaces above, one after 
"limits." and one before "bit ...". Also do you want to say " bit key ...".

* OCSP

129             responderURI, new OCSPResponse.IssuerInfo(null, 
issuerCert), null,

This will still throw NPE.

  169                 new TrustAnchor(issuerCert.getSubjectX500Principal(),
  170                         issuerCert.getPublicKey(), null),

Why are you using the issuerCert's key and dn as the trust anchor here? 
We don't actually know if that is the trust anchor, so I would just use 
null.
