Maybe... I while ago, the access to the EPSG factory was synchronized, so maybe
this error didn't occured at that time. Later one, the code has been made
concurrent, which may have opened a hole here.
My plan is to see if I can replace the HSQL database by the JavaDB one (a.k.a.
Derby). If it allows to use directly a database embedded in the JAR file (this
need to be verified), it may avoid this issue.
