Time spent: zilch, perhaps because most of my dependencies are java libs not scala ones. Like many Java devs starting out using Scala as a 'better java' which means adding more scala libs over time. It's definitely very pleasant to code in Scala vs Java, def more productive, to a surprising extent even. The compatibility issue needs to be addressed though.

Same here, zero time spent on this. Scala is a joy to program in. It's good to see these kinds of postings with complaints and suggestions. They'll move the language and the ecosystem forward.
