New Teiid Instance: Admin test doesn't indicate it's admin (and more)

MINOR ISSUE: When creating a Teiid server instance, clicking the Test button tests both the admin and user (JDBC) connections. Each test results in a dialog popping up. The user connection test clearly indicates it's for the user (JDBC) connection. The test of the admin connection never mentions the word "admin".

MAKING THINGS BETTER: Is it possible to have both tests reported in a single dialog? It would be far clearer to the user and less annoying since the user is not likely to expect the second dialog to appear.

THE BUG: If the admin connection test fails (bad username, for example), the JDBC connection test is also shown as failing, even when its connection information is correct
