Geek asks and answers

I'm asking about problems if I start using the standard Java 7 libraries?

I am writing a program that should monitor file system events on multiple platforms. 7 includes a new Java standard library WatchServicethat acts as an abstraction for different types of handlers file system events ( inotify, FSEvents, FileSystemWatcheretc.).

In this case, to compile code compiled with the Java 7 compiler, does the Java 7 JVM need to run?

If so, will I have all kinds of problems with client computers on which JVM 7 is not installed / is not available for this platform (older OSX, Windows XP, etc.)?
