/**
 * WindowsFileSaveTest simply opens an alignment file and then tries to save it.
 * This failed in Windows from 2.11.0 to 2.11.1.6 due to a combination of the
 * opening file handle being left open ad infinitum, causing the BackupFiles
 * operation of moving the saved (temp) file onto the original filename to fail,
 * but only in Windows. See: https://issues.jalview.org/browse/JAL-3628
 * https://issues.jalview.org/browse/JAL-3703
 * https://issues.jalview.org/browse/JAL-3935 These issues are really all fixed
 * by JAL-3703 This test is to ensure it doesn't start again, but note that this
 * test will only fail in Windows.
