Would be catastrophic for GeoServer scalability, big "no".
Suggestion: build a multithreaded test case showing the issue on a
supported version of GeoTools and let's have a look at it.

resetted it at runtime?).
If all you want is really to make that method synchronized (aka fast
workaround with little dev time investment),
you could also just fork the old version of GeoTools, or make uDig use its
own synchronized wrapper method,
or just have some operation to prime the CRS subsystem on startup (a
CRS.decode("EPSG:4326") for example).
