In my build script (in Subversion's tree at tools/dev/unix-build/) I pass the
following flags to Subversion's configure script if JavaHL is enabled:
--enable-javahl=yes --with-jdk --with-jikes=no \
--with-junit=$(DISTDIR)/$(JUNIT_DIST)
Did you also pass --with-junit?
For some reason I don't recall, my build script is fetching a self-hosted
junit JAR file from here: https://stsp.name/distfiles/junit-4.10.jar
(sha256: 36a747ca1e0b86f6ea88055b8723bb87030d627766da6288bf077afdeeb0f75a)
Given that you have self-compiled svn libraries in a non-standard prefix
you might also want to try setting LD_LIBRARY_PATH when invoking the tests.
Loading a wrong set of libsvn_*.so files would certainly cause issues, and the
ld.so runtime linker probably won't see JVM settings like -Djava.library.path.
env LD_LIBRARY_PATH="/home/nathan/ramdrive/svndev/prefix/svn-1.14.x/lib" \
make check-all-javahl
Hope this helps,
Stefan
