> We now test back-compat with "ant test-tag", which is very useful for
> catching breaks in back compat before committing.
> However, that currently checks out "src/test" sources and then
> compiles them against the trunk JAR, and runs the tests.  Whereas our
> back compat policy:
>   http://wiki.apache.org/lucene-java/BackwardsCompatibility
> states that no recompilation is required on upgrading to a new JAR.
> Ie you should be able to drop in the new JAR in place of your old one
> and things should work fine.
> So... we should fix "ant test-tag" to:
>   * Do full checkout of core sources & tests from the back-compat-tag
>   * Compile the JAR from the back-compat sources
>   * Compile the tests against that back-compat JAR
>   * Swap in the trunk JAR
>   * Run the tests
