title: Call variables created in JVM after JVM is closed in JPype
body: <p>I create a hashmap in JVM and want to access it after jpype.shutdownJVM, how can I do that?</p>
  
  <p>I know dict works as hashmap in python, I tried:</p>
  
  <p>jpype.startJVM(jpype.getDefaultJVMPath(),"-Djava.class.path=%s" % classpath)
  hashmap = jpype.java.util.HashMap()
  ...#insert pairs
  jpype.shutdownJVM()
  ...
  hashmap["key"]  this doesnot work.</p>
  
  <p>Thanks.</p>
