I see a few uses in the hotspot/ and jdk/ repos.
$ grep --recursive nativepath make */make test */test
hotspot/test/Makefile:# jtreg -nativepath <dir>
hotspot/test/Makefile: JTREG_NATIVE_PATH = -nativepath:$(shell
jdk/test/native_sanity/simplenativelauncher/ProgramTest.java: String lib
jdk/test/Makefile:# jtreg -nativepath <dir>
jdk/test/Makefile: JTREG_NATIVE_PATH = -nativepath:$(shell
