[DEV] Too small variable for OF-Port-Number

When connecting a HP-5500 to OD-daily-version (tested with the one built on Aug 16 together with the learningswitch-sample) i get following (slice of) output:

WARN o.o.c.sal.compatibility.NodeMapping - nodeConnectorId not supported (short): 9437207
java.lang.NumberFormatException: Value out of range. Value:"9437207" Radix:10

9437207 is a port number of the switch. After that message a NullPointerException follows. The corresponding variable should be an integer, because the current OF-specification defines at 7.2.1 "Port Structures" a 32-bits long port_no. Other tested switches work because they use small port numbers.

Full output of the java-errors are contained in the attachment.
