Fixed logging of java.sql.Date

[Hikarikun92]

Fixed logging of java.sql.Date objects by appending it before Log4J tries to call java.util.Date.toInstant() on it (see #1366).

@Hikarikun92,

Thank You for your contribution. Can you add some unit tests to prevent regressions?

[garydgregory]

-1: this PR is missing a unit test.

[Hikarikun92]

@ppkarwasz @garydgregory done, tested failing before & working after change. Could you please review it?

[ppkarwasz]

@Hikarikun92, it look good to me, thanks.

If there will be no objections I'll merge it in a couple of day.

[Hikarikun92]

@ppkarwasz Thanks for the merge! Just one question, the commit with the unit test is gone... is that normal?

[ppkarwasz]

@Hikarikun92, Ooops,

thanks for noticing, I must have lost them while locally rebasing. If you can push the tests on the 2.x branch of your fork, I'll pick them up later.

[Hikarikun92]

@ppkarwasz Done; should I open another PR? 2.x...Hikarikun92:logging-log4j2:2.x
