[birt-dev] Checkin: Fix a minor bug in JDBC connection

["Jianqiang Luo" <jluo@xxxxxxxxxxx>]

- Summary:
Fix a minor bug in JDBC connection

- Bugzilla Bug (s) Resolved:
Related with [126881]: Failed to close JDBC connection

- Description:
By test, I find connection can be successfully released for Oracle database. I think the problem is related with the bug reporter’s environment, but not caused by BIRT. To avoid potential issues, I add a line code to check whether connection is closed before attempting to do it.

- Tests Description:
Unit test, Manual test
