/**
 * Tests the gzip feature does not interfere with the ws-rm retransmission.
 * Note that the current retransmission logic isn't optimal (in some sense, wrong)
 * and stores the wire-message and retransmits this wire-message directly. This
 * approach is not practical when ws-security is enabled and each message needs to be
 * timestamped and signed. Therefore, the current retransmission logic needs to be
 * changed one day.
 *
 * Independently of this fix, this test verifies the gzip feature does not interfere
 * with retransmission.
