Subject: Native tests in the JDK?!
To: <jdk10-dev at openjdk.java.net>
8181147 added build infrastructure support to test native code in the
JDK core libraries, with a test specifically exercising String
encoding/decoding methods in libjava.
During review on core-libs-dev and build-dev the issue was raised that
this might surprise some users (and test systems) with some variant of
"Error: Use -nativepath to specify the location of native code", since
jtreg will expect you to build a test library and add it using -nativepath.
Consider this a late notification that this is something you might
unexpectedly run into.
Making it harder to test locally isn't nice, but thankfully there's new,
helpful support in the jdk10 makefiles to do all the required test setup
and build automatically (tips many hats at Magnus Ihse-Bursie), which
makes adapting to this (and any future additions) a breeze:
$ make run-test TEST=jdk/test/java/lang
Alternatively, if one has to run jtreg directly and can't be bothered
with any of this - because reasons - one may add the flag -k:!native to
exclude any and all native tests.
