Oh well, I give up, the code has such an number of indirections and SPI
lookups that I can't follow it not even with a debugger. I only spotted
a few things:
* in 2.4 the BufferedCoordinateOperationFactory uses an
AuthorityBackedFactory that in turns uses a LongitudeFirstFactory using
a OrderAuthorityFactory which in the end uses the FactoryOnHSQL
* in 2.3 under the same conditions the
BufferedCoordinateOperationFactory uses an AuthorityBackedFactory
using a DefaultFactory using a FactoryUsingSql
* in 2.4 the coordinate operation gets created fromlat/lon crs and
apparently a tentative to replace it with one that uses lon/lat
instead fails and this triggers the loop (that is, the replacement
still uses lat/lon...)
