Which JVM for ColdFusion development on Mac?

I’ve been having a lot of UI freezes lately on my MacBook Pro. The system will lock up for 20-30 seconds, with mouse movement, but no responses to clicks or the keyboard.

I’m suspecting that this is something to do with CF 8 and/or Eclipse on Apple’s Java 1.5 JVM. The freezes happen most often when one or the other of these applications are running.

Things seem a whole lot better when I roll back to Java 1.4, but CFEclipse stops working.

I’ve also found references to running CF 8 on Java 1.6. Maybe that’s the next thing to try.

  1. I am using version 1.4, ColdFusion 8 on the Power PC. Works wonderful, I have no issues using cfeclipse either, otherwise I would not get any work done.

    have things changed with the Mac book pro? I have been told that you can not use java 1.5 or higher? I might be really wrong on this, but it did not work for me, but when going to 1.4 I have not had any issues.

  2. In order to run Java 1.6 on OS X, you need to register for the Apple Developer Connection (ADC) and then you can download the JVM 1.6 PRE-RELEASE DEMO. This is not for production use and does not support a good number of JVM Args.

    All that being said, it is much faster than 1.5 and well worth the time to get it.

    As always though, caveat emptor.

  3. I would suspect Eclipse and/or CFEclipse, since SWT requires memory management outside Java’s own, due to the native component of SWT versus the pure Java&#8482 model of Swing. To anyone running CF I would suggest Java 5 (the 1.x thing is history) as there were massive improvements to the VM in the area of performance.
