Description
JCK test:
  api/java_io/Serialization/descriptions.html#FilePermissions

Regression test:
  test/java/io/pathNames/GeneralWin32.java

These tests fail on win32 only.

Modification of java.io.FilePermission.equals to show the contents of
this/that.mask, this/that.cpath, this/that.directory, and this/that.recursive,
indicates that the two tests fail due to path canonicalization problems.

EVALUATION The problem is that the implicit spec of FileSystem.canonicalize() is to throw an IOException if the file does not exist, but hits in the prefix cache are not testing for the existence of the file. The same problem exists in the UnixFileSystem implementation, though since that is only used for files within the JDK it isn't causing a failure in this JCK test. ###@###.### 2002-10-10 The above evaluation is incorrect. The root cause is that there are multiple subtle behaviors of FileSystem.canonicalize(), resulting in (variously) IOExceptions being thrown or other non-fatal results being returned from the operation. The problem is however isolated to the use of the prefix cache for canonicalization. The native code on Windows and Solaris has been examined and the new routine parentOrNull() has been restructured to bail out of complicated situations (like file names containing "..".) When parentOrNull returns null it simply uses the existing, expensive, canonicalization code. Now it is much more conservative in returning non-null results. Fixed in 1.4.2 b05. ###@###.### 2002-10-23
