FYI, 1.0 (incubating) was Calcite’s last release that supported 1.6. It was a long time ago (January 2015) [1] but 1.6 had reached end-of-life way before then (February 2013).
Avatica is now separate from Calcite, so you could attempt a back port of Avatica, removing JDK 1.7-specific features. This would be much less effort than back-porting all of Calcite.
