      Description

      I found a deadlock situation using JR 2.2.10, the problem is with DBCP 1.2.2 and is fixed in DBCP 1.3, JR trunk also uses DBCP 1.2.2 and should also be updated

      The ticket in dbcp is #DBCP-270, related tickets are #DBCP-65 #DBCP-281 #DBCP-271

      Stack trace of where my call is stalled:

        Any chance of a backport to the 2.4 branch ?

        this looks serious enough.
        I've ran all the tests with DBCP 1.3 and everything passes.

        fixed in revision 1296226.

        Added affects version 2.4 since it also uses DBCP 1.2.2.
