Description

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.
