Use Files.newInputStream(Paths.get(fileName)) instead of new FileInputStream(fileName). The FileInputStream and FileOutputStream classes contains a finalizer method which will cause garbage collection pauses. See [JDK-8080225](https://bugs.openjdk.java.net/browse/JDK-8080225) for details.
Use Files.newOutputStream(Paths.get(fileName)) instead of new FileOutputStream(fileName).
Use Files.newBufferedReader(Paths.get(fileName)) instead of new FileReader(fileName). The FileReader and FileWriter constructors instantiate FileInputStream and FileOutputStream, again causing garbage collection issues while finalizer methods are called.
Use Files.newBufferedWriter(Paths.get(fileName)) instead of new FileWriter(fileName).
* Use `Files.newInputStream(Paths.get(fileName))` instead of `new FileInputStream(fileName)`.
* Use `Files.newOutputStream(Paths.get(fileName))` instead of `new FileOutputStream(fileName)`.
* Use `Files.newBufferedReader(Paths.get(fileName))` instead of `new FileReader(fileName)`.
* Use `Files.newBufferedWriter(Paths.get(fileName))` instead of `new FileWriter(fileName)`.
