Certificates does not conform to algorithm constraints

I have a project that works fine in open source SOAPUI 5.1.2 but produces the following error in Ready!API 1.4.1:

Error getting response; javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: Certificates does not conform to algorithm constraints

I've commented out the # jdk.certpath.disabledAlgorithms=MD2 line in the java.security file for each product, as well as for java itself:

C:\Program Files\SmartBear\SoapUI-5.1.2\jre\lib\security

C:\Program Files\SmartBear\ReadyAPI-1.4.1\jre\lib\security

C:\Program Files (x86)\Java\jdk1.8.0_60\jre\lib\security

C:\Program Files (x86)\Java\jre1.8.0_60\lib\security

suggestions?  thanks.
