UnsupportedOperationException: Files.setPosixFilePermissions on Windows

[hohwille]

Expected behavior

Issue #132 should be fixed with #185
It seems this feature was not tested on Windows but Java does not support this on Windows.

Actual behavior

java.lang.RuntimeException: Unexpected error during interactive auto-completion
