Hibernate calls hang after giving message “opening JDBC connection”

Bug: Hibernate calls hang after giving the message “opening JDBC connection” in the logs. No exception/error message is thrown.

Reason: Connection timeout not set for the connection pooled datasource.

Solution: Set connection timeout for the datasource. In case of a basic datasource (apache), add and set property maxwait to the number of microseconds after which a timeout error is to be thrown.
