Hi, I have written a JMS Client, a plain Java Application using the Active MQ as the JMS Broker. I am not using the ActiveMQ's inbuilt facility of managing failover but have written that piece of code myself. The code works fine when run as a pure java application, but when I am invoking the same code from JNI ( from my C++ App) it crashes ( generates segmentation fault ). The crash is observed mostly when I connect/disconnect the Broker. Here is the PStack of the segmentation fault generated.
