jtreg-wrappers: Add runtime check for native clients

[zzambers]

This introduces custom jtreg properties, which track presence of native clients. Test can use them in @requires, so they are excluded, when native client is missing.

wicked! Will look into that tomorrow!

How does ti behave if the class is missing?
How does it behave when the testroot itself is missng, and jtreg will find unknown property?

[zzambers]

@judovana what do you mean by missing? Class SysDepsProps is part of testsuite. Jtreg reads information from TEST.ROOT and than compiles/uses it by itself.

If you would remove SysDepsProps or TEST.ROOT, tests, which use custom properties would indeed end with error..

I'm thinking what to expect, once sombody launches it in some weird way. If both are confirmed errors, I'm ok with that :)

Ok to merge by. Thanx for educative implementation!

• so if you remove TEST.ROOT or replace it with clean one, it is error
• if you remove just SysDepsProps.java it prints message about it missing, test using it will not run (properties are probably blank/nil)

However if you insist I can invert conditions to e.g. bin.gnutlscli == "true" -> bin.gnutlscli != "false" in which case tests will run with class missing

[judovana]

nn, thats ok. TY!

[zzambers]

too late :)

[judovana]

never to late O:)
