Anonymous TLS test in TestNetUtils doesn't complete normally if an URL connection was created before it. Also anonymous TLS doesn't work on Java 11+: #1303, but this issue is not the same, new failure affects all Java versions.

Test failure in this PR probably can be fixed by changing order of these tests in TestAll. But we definitely have problems in TLS code.

[grandinj]

yeah TLS is problematic, lets just re-order the tests to work around this

@katzyn thank you for assistance. I think my article may be interesting for you in terms of H2 extension function https://habr.com/ru/post/446380/

[katzyn]

Sorry, I don't understand what exactly do you propose. If you need some function that uses a third-party library, most likely such function will not be included in H2, but of course in can be loaded like any other user-defined function. For example, H2GIS has a lot of own functions.

@katzyn I am fully agree with you. But LATERAL https://postgrespro.ru/docs/postgrespro/11/sql-select# construction will be very helpful for user-defined table function.
