EVALUATION To fix 4185525 (Cannot create files with Unicode names in WinNT) for 1.3.1_07, WinNTFileSystem.java and associated native code changes were backported from 1.4.0 to 1.3.1_07. Unit test case and JCK - API tests went through without any problems. But I verified that the regression test fails as reported in this bug. It failes for file names such as "t.java/.\". In 1.4.0 codebase, constructors of FileInputStream, FileOutputStream and RandomAccessFile have been changed. String accepting constructors of these classes create new java.io.File out of the file name argument and pass file.getPath() to native open method. Whereas in 1.3.1 code, string is directly passed to native open method. Till 1.3.1_06 only Win32FileSystem was supported. This file system itself handled cases such as t.java/.\. The new WinNTFileSystem does not handle such names. The fix is to change constructors of FileInputStream, FileOutputStream and RandomAccessFile classes along the lines of 1.4.0 code. Please refer to "Suggested Fix". I verified that this fix. I'll work on getting this fix into 1.3.1_07. ###@###.### 2002-11-14
