> Several classes in _opennnlp.tools_ exist which read files via {{FileInputStream}} *without* using buffered IO. If IO is not buffered, this can impose a (high) performance penalty as the JVM will have to use native (JNI) calls more often (resulting in more sys-calls to the OS).
> We can avoid that by adapting existing classes to use {{BufferedInputStream}} or {{BufferedReader}} more consequently.
