After upgrading to Java 1.8.0_131 from Java 1.8.0_121-b31, the following is
observed when trying to run the application:

security: WARNING: The following resource is signed with a weak signature
algorithm MD5withRSA and is treated as unsigned:
http://XXXXX:8080/xxxx/xx/xx.jar This algorithm is now disabled by the
security property:
jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024

As a workaround, they added http://XXXXX:8080 to the exception site list.
However this didn't work.
