I wrote a unit test:
https://github.com/nicolas-f/h2database/commit/ea22bd7532150a17a1e92b009a98bf389a7f3f7f#L1R533
If you take two geometries A "POLYGON ((67 13, 67 18, 59 18, 59 13, 67 13))
and B "POLYGON ((67 13 , 67 18 5, 59 18, 59 13, 67 13 ))"
The result of A.equal(B) is true.. Then the cache system of Value will keep
only A and garbage B. The only way to fix this issue is to do a binary
comparison in ValueGeometry.equals( )
