Better exception logging in crypto code

Debugged an issue recently related to crypto provider jar file loading. Some of our crypto code handles failures silently. We should fix that.

src/share/classes/javax/crypto/JceSecurity.java

    static synchronized Exception getVerificationResult(Provider p) {
        Object o = verificationResults.get(p);
        if (o == PROVIDER_VERIFIED) {
            return null;
        } else if (o != null) {
            return (Exception)o;
        }
        if (verifyingProviders.get(p) != null) {
            // this method is static synchronized, must be recursion
            // return failure now but do not save the result
            return new NoSuchProviderException("Recursion during verification");
        }
        try {
            verifyingProviders.put(p, Boolean.FALSE);
            URL providerURL = getCodeBase(p.getClass());
            verifyProviderJar(providerURL);
            // Verified ok, cache result
            verificationResults.put(p, PROVIDER_VERIFIED);
            return null;
        } catch (Exception e) {
            verificationResults.put(p, e);
            return e;
        } finally {
            verifyingProviders.remove(p);
        }
    }

==
we should log issues which are detected with provider jar files.

There may be other related cases to be examined.
