   Apologies for digging up an old thread, but i'm a little confused as to how the connection pooling works within the ActiveMQ pool. If the connection pool borrowObject timesout we will be stuck in the while loop until there is a free connect to borrow from the pool no? 
   
   i.e., 
   
   `connection = connectionsPool.borrowObject(key);`
   
   Throws a _Timeout waiting for idle object_ then we will never exit

> A maxPoolSize of 1 can cause starvation during createConnection if the only connection gets evicted concurrently since borrow method of pool has no timeout waiting forever.
> Maybe introduce a new variable connectionTimeout with default 30000ms.
