When implemented File I/O in base, and we used PosixFilePermissions through out. An OS check should be done and avoid that code path and replace it with windows equivalent version.

The method is fileChannelOpen in libraries/base/java-utils/Utils.java. Would you be interesting in taking a stab at this?

@rahulmutt yes, it would be interesting for me to take this bug and to try to fix it.

This should be fixed now.
