      Description

      We had a situation a JT ended up in a state where a certain user could not submit a job, due to an NPE on the following line in sendParam:

      synchronized (Connection.this.out) {
      

      Looking at the code, my guess is that an RTE was thrown in setupIOstreams, which only catches IOE. This could leave the connection in a half-setup state which is never cleaned up and also cannot perform IPCs.
