Facing issue with JOIN Query if the following Entity is preset in a package starting within.
There are many popular domains like "in", "net.in", "co.in" would have package starting "in"
however IN also a keyword causes shift-reduce conflict. To avoid would escape it with a quote of the fully qualified class name of the entity.
Following stack trace

Where us if I rename the package with *inm.musicmaster.db.Models* there is no error. but that is not the correct workaround. |
