Summary: Clarification of "1.6" vs. "6" in SourceLevelQuery

Description Jesse Glick 2011-09-19 18:36:13 UTC 
SourceLevelQuery.getSourceLevel says to see tool docs for acceptable return values; technotes/tools/solaris/javac.html#options gives "6" as a synonym for "1.6", etc. Yet the SOURCE_LEVEL pattern will reject this if supplied by SourceLevelQueryImplementation or SourceLevelQueryImplementation2.Result (whose Javadoc lists the 1.x formats as examples but is otherwise silent on acceptable values).

Since API clients should not have to deal with synonyms, and SPI implementations such as Maven's might be coming across e.g. <source>6</source>, I would propose that SourceLevelQuery accept \d+ versions but quietly prefix them with "1." before returning.

Alternately, document that SLQI must return versions in canonical form, and make impls such as MavenSourceLevelImpl do this conversion.

Yes. It's how it should work.
