RFR: JDK-8230920 : jpackage problems when -input dir contains any files with "cfg" extension.

[Alexey Semenyuk]

One thing that I just notice is that you introduced caching in 
AppImageFile file. The caching doesn't take into consideration that 
different values can be passed in AppImageFile.get() function. So if the 
function would be called multiple times with different values of 
`appImageDir` parameter the same AppImageFile instance will be returned 
in all the calls. Unfortunately unit tests didn't catch this. I suggest 
you either fix the caching logic or get rid of it in AppImageFile class.
