Yeah, while doing more testing it seems to depend from where the ClassNotFoundException is thrown. What I was trying to do at first is to call extend-type on a Java class only if it exists. Surrounding extend-type by a try..catch clause doesn't work here. So I tried to simply type:
user> (try org.postgresql.PGConnection (catch ClassNotFoundException e :catched)) ; Evaluation aborted. And, as you see, the try..catch didn't work either. But I just found out that when using Clojure internal classForName method it can be catched: user> (try (clojure.lang.RT/classForName "org.postgresql.PGConnection" ) (catch ClassNotFoundException e :catched)) :catched So we could always use RT/classForName to detect what classes are available. Do you think the extend-type thrown exception can possibly be fixed or is it a fundamental limitation?
