--- Comment #8 from Jung-uk Kim <jkim at FreeBSD.org> ---
Please note statically linking jli was a hack to work around a launcher
problem.

$ /usr/local/openjdk8/bin/java -version
openjdk version "1.8.0_31"
OpenJDK Runtime Environment (build 1.8.0_31-b13)
OpenJDK 64-Bit Server VM (build 25.31-b07, mixed mode)

Let's make a symlink and try the link.

$ ln -fs /usr/local/openjdk8/bin/java .
$ ./java -version
openjdk version "1.8.0_31"
OpenJDK Runtime Environment (build 1.8.0_31-b13)
OpenJDK 64-Bit Server VM (build 25.31-b07, mixed mode)

This works.  However, the following fails:

$ $PWD/java -version
Shared object "libjli.so" not found, required by "java"

That's because the actual executable was linked with '-z origin', i.e.,

$ objdump -p /usr/local/openjdk8/bin/java | grep ORIGIN
  RPATH       $ORIGIN/../lib/amd64/jli:$ORIGIN/../lib/amd64
  RUNPATH     $ORIGIN/../lib/amd64/jli:$ORIGIN/../lib/amd64
$ ldd /usr/local/openjdk8/bin/java | grep libjli
    libjli.so => /usr/local/openjdk8/bin/../lib/amd64/jli/libjli.so
(0x800a36000)
$ ldd $PWD/java | grep libjli
    libjli.so => not found (0)

As you can see, our rtld(1) resolves $ORIGIN differently if it starts with `/'.
 Arguably, it is a bug in rtld, though.
