Anyone has time to help review this fix? After the support for 
RSASSA-PSS keys is added, when parsing the DER encoding, the key 
algorithm is based on the parsed algorithm oid/name. However, an 
exception is thrown if the parsed algorithm oid/name is neither RSA nor 
RSASSA-PSS. For this particular report, the algorithm oid is which is unsupport/unrecognized by JDK. In earlier 
releases, the bytes are parsed but key algorithm is always "RSA".

To maintain this backward compatibility behavior, I changed the current 
impl to set the key algorithm upon key construction time w/ a KeyType 
argument (RSA or RSASSA-PSS) even when DER encoding is given. After 
parsing the DER encoding, for non-RSA keys, the parsed algorithm 
oid/name should match the given key type, otherwise an exception is thrown.

Mach5 run is clean.
