So in conclusion, the new failure is an accidental side-effect of
improvements in the use of EPSG geodetic dataset by Apache SIS. There is
two possible fixes:
1. When an operation method is not implemented in SIS, ignore it like
SIS 0.7 did and declare an accuracy of 3 km (this is an arbitrary
value based on the worst case scenario I have seen so far).
2. Do not change current behaviour (i.e. continue to try to follow
strictly EPSG path) and finish implementations of coordinate
operation methods listed at
https://issues.apache.org/jira/browse/SIS-212 (with addition of
“Madrid to ED50 polynomial” to this list if not already there).
I would prefer option 2, but it may take some time and I do not know how
important are the operations that currently fail?
