This unfortunately causes the file link in /proc/curproc to return "unknown" as it uses vn_fullpath which relies on the namecache fields to be set correctly. Java uses /proc/curproc/file to know where to find its libraries and doesn't expect the "unknown" return value returned when using ZFS (due to vn_fullpath failing). The attached patches to the java/jdk15 port fixes this issue but it doesn't fix the root of the problem. Would it be possible to add support in dnlc for updating the VFS namecache fields or to add knowledge of dnlc into vn_fullpath?
