--------------------------------------

             Summary: PID and Platform info should be cached and reused for 
subsequent connections
                 Key: QPID-4288
                 URL: https://issues.apache.org/jira/browse/QPID-4288
             Project: Qpid
          Issue Type: Improvement
          Components: Java Client
    Affects Versions: 0.18
            Reporter: Rajith Attapattu
             Fix For: 0.19


While investigating the reasons for the java client occasionally not being able 
to negotiate the connection within a reasonable time, we noticed that there is 
often a time gap between receiving connection-start and the client responding 
with connection-start-ok.

Upon further investigation it appears that getPid() and getPlatformInfo() is a 
contributory factor. 

These values are per JVM and there is no reason to fetch them for every 
connection. Instead we should fetch them in a static block and then return the 
cached value when the getters are called.
