Description

JtsSpatialContext.getGeometryFrom(shape) doesn't support dateline crossings for rectangle and circle. This condition won't appear for Lucene's RecursivePrefixTreeFilter but it might for the Jts strategy Ryan wrote.

It shouldn't be hard.

Start by locating JtsSpatialContext.getGeometryFrom(shape) and inspect how rectangle and circle shapes are converted when they cross the dateline. Confirm the expected geometry behavior for those crossings and add coverage for the affected cases; done means both shape types are handled correctly.
