Motivation: OOME is occurred by increasing suppressedExceptions because other libraries call Throwable#addSuppressed. As we have no control over what other libraries do we need to ensure this can not lead to OOME. Modifications: Only use static instances of the Exceptions if we can either dissable addSuppressed or we run on java6. Result: Not possible to OOME because of addSuppressed. Fixes https://github.com/netty/netty/issues/9151.
