It's problematic when the spec is clear that accessing a file with the empty path is equivalent to accessing the current directory. So I think this more as a way to get access to the current directory to fail. In any case, I think this is a forced move as we under estimated the compatibility impact of fixing the long standing inconsistency. src/java.base/share/classes/java/io/FileSystem.java line 41: > 39: > 40: protected static final boolean FAIL_IF_EMPTY_PATH = > 41: Boolean.getBoolean(FAIL_IF_EMPTY_PATH_PROPERTY); This doesn't need to be protected as FileSystem is package-private so can't be extended by classes in other package. I assume you make it protected to make it clearer that it intended for concrete subclass implementations. ------------- Marked as reviewed by alanb (Reviewer).
