Hi, I'm using ActiveMQ 5.4.3 on 32-bit Java, and want to upgrade to 64-bit Java. I notice that in this version, 64-bit wrapper is not provided yet. Are there any issues, bugs, or performance related problems reported on using 32-bit wrapper for AMQ on 64-bit Java? I'm currently getting below message from the wrapper when I start it on 64-bit Java:

Basically, I'm seeing slower performance in enqueing/dequeing messages on 64-bit Java during testing, but I am not sure if this is because I'm using 32-bit wrapper or 64-bit JVM is just slower. If neither, are there any settings that we could adjust?
