WebLogic EJB call timeout

If you get often this type of stuck threads:

"[STUCK] ExecuteThread: '170' for queue: 'weblogic.kernel.Default (self-tuning)'" daemon prio=10 tid=0x00002b4f841f1b20 nid=0x5763 in Object.wait() [0x00002b4f8c842000]
   java.lang.Thread.State: WAITING (on object monitor)
 at java.lang.Object.wait(Native Method)
 - waiting on <0x0000000776826778> (a weblogic.rjvm.ResponseImpl)

you might want to set these 2 parameters (this for WLS 10.3.6 )
-Dweblogic.rmi.clientTimeout=valueInMilliseconds
weblogic.jndi.requestTimeout=valueInMilliseconds

The reason of that WAITING is that there is a synchronized blog followed by an Object.wait(timeout):

  private void waitForData()
  {
    int i = 0;
    synchronized (this)
    {
      long l1 = this.timeout;
      while (!isAvailable()) {
        try
        {
          int j = 0;
          long l2 = System.currentTimeMillis();
          wait(l1);
          if (this.timeout > 0)
          {
            long l3 = System.currentTimeMillis() - l2;
            if (l3 >= l1) {
              j = 1;
            } else {
              l1 -= l3;
            }
          }
          if ((!isAvailable()) && (j != 0))
          {
            this.t = new RequestTimeoutException("RJVM response from '" + this.rjvm + "' for '" + (this.md != null ? this.md.toString() : "null") + "' timed out after: " + this.timeout + "ms.");

            i = 1;
          }
        }
        catch (InterruptedException localInterruptedException) {}
      }
    }
    if (i != 0) {
      this.rjvm.removePendingResponse(this.id);
    }
  }
