Error description
NullPointerException could be thrown at com.ibm.ejs.j2c.ConnectionManager.allocateConnection. This is because when Thread A enters into allocateConnection(), another thread(Thread B) could possibly null out the pool manager reference in connection manager. In the end, a NullPointerException is thrown when Thread A attempts to use the reference to pool manager..
