Is it somehow possible to test if a java.io.File is currently open in another process by any process ? I am using Java 7 and target platforms are Linux/Windows/Mac.

There is no easy way in Java to go about this that will work reliably across different platforms. Depending on what you’re trying to do, you might be able to patch together a series of try/catch statements which ostensibly work for most cases on most file systems, but you can never have full certainty that the next situation it encounters won’t throw it off.
If you do end up going this route you want to ensure that when there is any doubt, it fails fast and doesn’t get into a situation where it thinks a file is not open when it really is. My advice would be to see if there is any way you can possibly work around having to do this check.
