jvpp: suppress unwritten fields warrning found in DTO's hashCode
DTOs fields are initialized by generated JNI code, so we can safely ignore FB.UWF_UNWRITTEN_PUBLIC_OR_PROTECTED_FIELD. Coverity uses FindBugs to analyse Java code, so it should be possible to suppress some of the issues that are false positives or intentional.
