Forms Application does not run anymore after java upgrade to 1.8_131 on client

If Your Forms application cannot be started after a java upgrade to 1.8_131, please check this Oracle Community Thread: https://community.oracle.com/thread/4037666

In short:
Reason is: With Java 8u131, MD5-hashes are no longer accepted in certificates
If using Forms 12c, no action has to be taken - if using Forms 11 you'll have to apply patch 19933795

One possible workaround (not recommended!): Adapt the appropriate java.security file in the client's java home:
jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024
to
jdk.jar.disabledAlgorithms=MD2, RSA keySize < 1024
