next is used as an entry in the hibernate.properties file

hibernate.connection.url
jdbc:firebirdsql:localhost/3050:/D:\databases\test\B2.gdb

when the program starts, I get: Resource Exception. Unable to
complete network request to host ...


In the log file this property looks like this, which is of course wrong:
jdbcUrl -> jdbc:firebirdsql:localhost/3050:/D:databases estB2.gdb

How can I fix this.
