Hmm, not sure why ECUtil discards the exception and returns null...
I plan to add a check inside SignatureUtil to check for null and error
out to make the EC case consistent with others. Rerunning mach5 now to
double check.
Thanks for noticing this.

SignatureUtil::getParamSpec(String,byte[]):

ECUtil.getECParameterSpec() could return null when
"parameters.getParameterSpec(ECParameterSpec.class)" throws an
InvalidParameterSpecException. So the behavior is now different from the other
getParamSpec(String,AlgorithmParameters) method where the exception is wrapped into a
ProviderException. Does this matter?

Right, based on the current impl, a simple "==" seems to work as it's the same
NamedCurve instance inside CurveDB. Well, I could also do a bit of code refactoring and
add an equals utility method to ECUtil so this may work better with 3rd party provider's
impl.

What does "sigParams.equals(keyParams)" mean here? What is the getClass() of
those 2 ECParameterSpec objects?
Or maybe you mean "==" because it is always a NamedCurve stored in CurveDB?

Hi
Any one can help reviewing this fix? Some ECDSA certificates contains signature
algorithm identifiers with non-null parameter bytes. Before RSASSA-PSS support,
these parameter bytes are ignored, however, after RSASSA-PSS support, the
parameter bytes are passed to the underlying signature impl and this breaks the
ECDSA certificate verification. In order for the verification to succeeds, the
SignatureUtil class needs to be able to parse the parameter bytes for ECDSA
certificate and that SunEC provider needs to accept non-null signature
parameters.

Mach5 run is clean.
