Re: [dsdp-mtj-dev] Preverification support on MTJ

Eric,

Sorry for not getting a response back on this for a while. Part of it is that I've been busy and part was that I was doing a bit of experimenting.

I have two questions for multiplatform support:

1. Is it just the preverifier that is the issue, or are there other components we need to worry about as well?


Given projects like MPowerPlayer and microemu, Mac has basic emulation functionality. These emulators are limited in their JSR support, but are probably "good enough" for now. The problem does tend to be with the preverifier.

2. Should we ask Sun if the existing PhoneME preverifier can also be released as EPL code within MTJ?


You can ask, but my guess is that they will say that it is already "open source". The problem is that it is GPL.

My thought is we must have Windows, Linux, and Mac support in MTJ, the real question is the best way to get there (fast).....


I agree. I did some experimentation and found that building the preverifier from source for the Mac was not terribly difficult. This might be a reasonable starting point... I can always provide it as a download for people to avoid EPL licensing issues with the GPL code. To make user of this, it would be necessary to allow an arbitrary external preverifier to be associated with mpowerplayer and microemu projects. This is not supported by the EclipseME code on which MTJ is based. The best thing we could do would be to allow the user to choose an external preverifier or the built-in preverifier for *any* device.

In terms of the built-in preverifier, I had a quick look at ASM 3.0 in the process of doing something else for work. It appears there are actually some better API's in there that could be used to "fix up" the current implementation. Unfortunately, that may not be doable in the short term.

In summary... I think there are some reasonable options for Mac, but one of them is going to force the user through more hoops and the other requires more work on MTJ part.
