Description

I've encountered multiple SSL errors when running the Accumulo funtests with jdk 1.8.0_77-b03: "javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: Certificates does not conform to algorithm constraints" and "javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Algorithm constraints check failed: MD5withRSA".

The first error appears to be related to AccumuloSSLTestBase using X509ExtendedTrustManager instead of X509TrustManager:

The second seems to be due to SecurityUtils specifying a default hash of md5 when signing certs:
