Maven 2 quirks and the "bandwagon"

I recently found myself developing (and using) a lot of small tag libraries to make my life easier when it comes to developing my web applications. The only thing that really gets me is that when I write these tag libraries, I have to manually update all of the TLD (tag library descriptor) files that are necessary for using the tags in JSPs. This irks me and it occurs to me that there's no reason I can't have Maven generate the TLDs for me based on annotations I place on the tag classes. The only problem with this is that no such plugin exists, so I figured that as a foray into Maven plugin development, I'd try making such a plugin as my first try. It is then that I ran across a rather large and bothersome quirk with Maven : it's not entirely ready for Java 5 and up. In fact, rather than using proper Java 5 annotations, it uses XDoclet comment annotations to provide metadata for building plugins, but that's not the quirk. The real quirk is that it can't handle having Java 5 annotations in the same project as the plugin. It can handle Java 5 enums just fine, but not annotations, which seems rather strange to me.

This is all part of the bigger problem of companies not keeping themselves up to date with the latest Java technology and staying with Java 1.4.2 and earlier. Sun has done a great job of maintaining backward compatibility, and there's (almost) no reason that companies shouldn't be upgrading the JVMs on their servers to the latest and greatest versions. The only real reason I can think of is that somewhere in their code, they've used variables named 'enum' which becomes a Java keyword in Java 5 and up (aka Java 1.5, 1.6, etc), and this can be mitigated by refactoring the code. Hell, Eclipse makes that job quick and easy, especially when you really know your keyboard shortcuts. I'm fortunate enough to be able to use Java 6 (and very quickly upgrade to Java 7 as soon as it's released and stable). As much as this is going to make me a snob, I'm getting really tired of being dragged down by other people's need for backward compatibility (and hence also tool developers' appeasement of these people which then affects me). Seriously people, get your act together.
