explorer fails to run on OSX's JDK6

[batalbot]

When attempting to run explorer on JDK6 of OSX, it fails with the exception shown below.  In the past this was easy enough to avoid since Leopard kept the default JDK set to 1.5; however, Snow Leopard changes the default JDK to 1.6 and also completely removes JDK 1.5 and 1.4.  This happens when java is started in the default 64-bit mode as well as when forced into 32-bit mode.

It's probably an issue in JIDE from the looks of the stack trace.  The stacktrace is from swiftmq 7.5.2.

This was actually fixed in 7.5.0. May be you're using an old jide.jar?

Not unless the 7.5.2 distribution has the wrong jide.jar

Just downloaded and tried this with 7.5.3 and it works.  Turns out that the jide.jar file is different in 7.5.3 compared to what is all previous 7.5.x releases even though it's not mentioned in the release notes.

Sorry, I was wrong; it wasn't fixed in 7.5.0 but as a hot fix with updating the current 7.5.2. The new jide.jar was included in the updated 7.5.2 (from our website) and as a patch. The news was sent June 22:

Betreff: [SwiftMQ News] SwiftMQ Explorer on Mac OS X with the new Java 1.6.0_13


(The following apply only for Mac OS X 64-bit users running Java 1.6.0_13).

On June 15 Apple released Java 1.6.0_13 via Software Update. It fixes a few security issues in
Java but more importantly, SwiftMQ Explorer may fail to start because the jide.jar is not
compatible with this Java update.

We provide a new jide.jar which fixes the problem. Download here:

http://www.swiftmq.com/macpatch/

Replace the old jide.jar with the new one and restart SwiftMQ Explorer.

The current SwiftMQ release 7.5.2 has been updated with the new jide.jar as well.



Please don't reply to this eMail.

Ahh, thanks for the clarification.  I guess I missed that announcement since I was out of town at that time.  Glad there's a good fix though.
