When a Java 2 security manager is enabled, an AccessControlException is thrown while creating a new Client instance:

Stack:

It should be possible to avoid this in ManualClosingApacheHttpClient43Engine.java by wrapping the static block for retrieving the processId inside a doPriv block similar to this:

static
{
   try {
     processId = AccessController.doPrivileged(new PrivilegedExceptionAction<String>() {
      @Override
       public String run() throws Exception

{        return ManagementFactory.getRuntimeMXBean().getName().replaceAll("[^0-9a-zA-Z]", "");        }

     });
   } catch (PrivilegedActionException pae)

{      throw new RuntimeException(pae);    }

}
