um, I'm pretty sure that dll/so doesn't work without the rest of the JRE
around it.  I would think the platform packager would need to bundle the
whole 'private' JRE they chose including that jvm.dll/so, and install
that somewhere in or around the postgres code tree, along with the
pljava.so/dll that binds it all together, if the user chooses to install
pljava support.
