Rare NegativeArraySizeException

[bubbleguuum]

Using v0.12.0, I've an automated rare crash report from a user of my app:

 java.lang.NegativeArraySizeException: -88
                at com.rapid7.client.dcerpc.transport.RPCTransport.call(RPCTransport.java:81)
                at com.rapid7.client.dcerpc.service.Service.call(Service.java:46)
                at com.rapid7.client.dcerpc.service.Service.callExpect(Service.java:55)
                at com.rapid7.client.dcerpc.mssrvs.ServerService.access$600(ServerService.java:58)
                at com.rapid7.client.dcerpc.mssrvs.ServerService$GetSharesRequest.call(ServerService.java:296)
                at com.rapid7.client.dcerpc.mssrvs.ServerService.getShares1(ServerService.java:122)

Looking at RPCTransport.java:81, we have final byte[] packetInBytes = new byte[getMaxXmitFrag()];.
So getMaxXmitFrag() is returning -88. Probably a bug in whatever is providing this value, that is not checked that it is valid by the lib (> 0).

All I know is that the queried device is some sort of router with SMB and that at the time of the crash there's a session connected to it with these characteristics:
NegotiatedProtocol{dialect=SMB_3_0, maxTransactSize=65696, maxReadSize=65564, maxWriteSize=65584}
