In JBSE master there is not yet the implementation of a native method that is present only in the Windows version of class java.io.FileDescriptor, and that is invoked during <clinit>. Since file descriptors are initialized on virtual machine bootstrap, until we add this native method implementation JBSE cannot boot under Windows. Of course there could be more unimplemented natives under Windows (and Linux), so we need to check.
