/jre/lib/security/java.security file as follows (both steps are required):

Add MD5 to the jdk.certpath.disabledAlgorithms property - for example,
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024, MD5

Add MD5withRSA to the jdk.tls.disabledAlgorithms property - for example,
jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768, MD5withRSA
