[rmi] supressStackTraces does not suppress suppressed exception

[Stuart Marks]

Hi Bernd,

How very interesting. Thanks for pointing this out. You're right, 
suppressStackTraces should probably also suppress the stack traces for 
suppressed exceptions. (Kind of funny given the names, but the word "suppress" 
is being used in two different senses here.)

I've filed this bug to track the issue:

https://bugs.openjdk.java.net/browse/JDK-8144968

I'm not sure if there's anything to be done about SQLWarning though.
