I think their strategy is fairly explicable, but I think they did make some mistakes with some of the specifics (filename-based automodules!). There's a pattern that Oracle tend to follow: They solicit opinions from everyone vigorously, and then they implement the smallest possible subset such that the fewest possible people are pissed off by it. If there's a possibility of doing something wrong, nothing is done instead. Being incomplete and "too strict" is considered preferable to any kind of maintenance burden or making a mistake that people then come to depend upon. Then, after a version of something is released, the dust settles and the people that are still complaining after a year or so of implementation are asked for comments again. The process repeats! You can see this going on with quite a few of their projects. A good example of this with the JPMS is that there was a vigorous insistence that the module graph be a DAG. Now, some way into the first year, it's going to be allowed to be cyclic but only at run-time. I think the process does eventually produce results, but it takes a long time to get there and demands a lot of patience from the people involved. Most VM features seem to start off utterly spartan and then grow to support the use-cases that people wish they'd supported right from the start. Java in particular has awful press, and a userbase that seems to become incomprehensibly enraged over all good news and all bad news indiscriminately, so that doesn't help the perception of the process (or the results). I think the key will be to continue complaining for as long as it takes to get better interop between OSGi and the JPMS. :) -- Mark Raynsford | http://www.io7m.com
