Where's System.loadLibrary() in FileInputStream?

Thread view:

I got a good look in the source code for FileInputStream in the J2SE
1.5.0 and noticed a few native methods, including open(), read(), etc.
After looking at the code more, there isn't a System.loadLibrary
anywhere where i would normally see if a class used JNI. How does
FileInputStream know what native library to load then?

It isn't necessary to explicitly load a library for every class that
uses native code, since the JVM executable already holds much of the
native code used by the standard classes.
