I don't follow... If a user came to you and said I want to run BibleDesktop, and they have MS-DOS, you would tell them you can't (or you might have to run the very old BibleDesktop 1.0).
If they told you they have Windows 98 with Java 1.4 and 256mb or memory, you would say you can run BibleDesktop 2.0 (which includes Lucene 2.0). If they told you they have Windows XP with Java 1.5, you would say you can run BibleDesktop 3.0 (which includes Lucene 2.1). Certainly seems like a packaging/marketing issue for you. Your users would not know if they were running Lucene 1.4, 1.9 2.0 or 2.1, nor would they care. -----Original Message----- From: DM Smith [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 20, 2006 5:17 PM To: java-dev@lucene.apache.org Subject: Re: Results (Re: Survey: Lucene and Java 1.4 vs. 1.5) On Jun 20, 2006, at 5:09 PM, Otis Gospodnetic wrote: > ----- Original Message ---- > From: DM Smith > > > On 6/20/06, Otis Gospodnetic wrote: Sorry, for some reason my Yahoo > email doesn't prepend ">" on replies, so I'll use "OG" for my lines. > > In my situation, I am constantly working on improving an open source > application.

Each user of BibleDesktop has to decide for themselves. Users of MacOS 10.3 and earlier are stuck using Java 1.4. Users that have upgraded to Java 5 get the advantages of that runtime.

That's the core argument that you are making and it is a good one. If it could be designated in Jira whether the attachment were Java 5 then others (perhaps myself) could take the patch, downgrade it and attach it to the same issue. It sure would beat forking the project. > > How many external contributions are to the "core" Lucene? > If the "core" Lucene contribution can be applied and then > "downgraded" to Java 1.4 easily, what harm is in that? > > OG: I don't know the number, but JIRA would be the place to > look. My guess is about a dozen or more people. > Steve Rowe found something that can "downgrade" 1.5 code to 1.4 and > looks promising. If so then perhaps the committers could run the code through it after applying the patch. Then the contributers would not be adversely affected. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
