JDK-4041126 - java.io.File.delete: NT Permission problem
Description
Both File.canRead() and File.canWrite() ignore DACL information for NTFS
partitions on Win32 systems. This can cause canRead()/canWrite() to incorrectly
return true if a file is readable/writeable according to its attributes but
not according to its DACL.
Comments
SUGGESTED FIX Change canRead()/canWrite() so that DACL permissions are taken into account. The union of both attribute and DACL permissions should be taken when determining read/write access.
