As far as I can see, the main point of difference is what is contained in them? Any guidelines as to which should be used when? And what then is a "cache pool" which is referred to in a numb...

Based on an answer I got here, I started to give commons-pool a serious look. My last experience of using it was around 2003, probably version 1.1 or 1.2. Its main user, DBCP, is considered by many as flawed and to be avoided. Does anyone uses commons pool in production to write pool of your own? What is the best pool type to use? I pl...
