Does Oracle PreparedStatement.executeUpdate() handle connection pool exhaution by throwing an instance of SQLException?

Will Oracle PreparedStatement.executeUpdate() API throw an exception of type SQLException if the connection pool is exhausted?

My application codes (KMDatabaseDAO.insert()) is calling the Oracle PreparedStatement.executeUpdate() API, however, the method seems to only throw an SQLException, because existing production codes have pretty messed up the logging level, i am unable to recover the actual logs printing out.

Below is the thread dump taken.

Oracle PreparedStatement API

The fact that you have a PreparedStatement means that you've already retrieved a connection from the pool, so no, the pool is not exhausted, and executing a PreparedStatement can't exhaust it because doing so doesn't retrieve another Connection from the pool.
