AbstractDatabaseEngine.getConnection() - Debug log messages are incoherent and number of attempts is exceeded

[tmartinsfdz]

In the function getConnection(), for a number of attempts equal to 10 and opening the log system for the debug mode it is noticed that the debug messages of attempt 5 and 9 are not presented (number of the middle and penultimate attempt), and in these attempts it only appears an error message that mentions that only X attempts are missing. Another behaviour noticed in this function, is that for a determined number of attempts, the function always executes one more attempt.
