Use a componentized build system to automatically port Java™ projects with native extensions on heterogeneous UNIX® platforms. Today, many large-scale Java systems running on UNIX-like platforms require third-party native library support, or you have to develop your own native components. Many utilities and system calls on these platforms do not have corresponding Java wrappers. Constructing a "Write once, run anywhere" Java application under these environments requires maintenance of separate native source sets, and integrating a separate build system for every platform has many shortcomings.more
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
