Frank,
As I’m sure you can understand, we work to enhance MyEclipse based on what will help our global user base the most, based on their feedback. While we’d love to be able to work on everything everyone wants simultaneously, obviously given timeline and resource constraints we are forced to make some trade-offs. Toward that end we basically prioritize as follows:
1) High-demand feature availability on all supported platforms. For example, this includes a profiler, UML 2, and Struts 2 (among other additions) on all platforms
2) Support new, previously-unsupported platforms is enqueued and prioritized based on availability of pre-requisites and end-user impact.
For 64-bit Mac support we first needed Eclipse 3.5 to be released since that provided the support for 64-bit Cocoa. Our work load for the 8.0 release (first 3.5-based release) was already set at that time. 64-bit Mac support didn’t make the list for 8.0 because it would have meant taking resources away to work on just that for a small group of Mac users versus new features for the entire user community. To put it in perspective, the MyEclipse user base is 85% Windows, 10% Linux and 5% Mac. And, since the Snow Leopard users can still run MyEclipse 8.0 in 32-bit mode there is a simple work around in place until we can put the infrastructure in place to support an additional platform (which is no small task) in the 8.1 release.
I realize you’re probably still disappointed that 8.0 will not run in 64-bit mode on a Mac, but it’s my hope that at least you now have enough background to understand why it was pushed to 8.1.
