java.io.FileSystem class uses two system properties for enabling/disabling performance
optimisation for file names canonicalization, but these properties cant be set apart.

Here is a part of java/io/FileSystem.java:
=====
    208 static boolean useCanonCaches = true;
    209 static boolean useCanonPrefixCache = true;
[...]
    221 static {
    222 useCanonCaches = getBooleanProperty("sun.io.useCanonCaches",
    223 useCanonCaches);
    224 useCanonPrefixCache = getBooleanProperty("sun.io.useCanonPrefixCache",
    225 useCanonPrefixCache);
=====
Note, that these values are retrieved via different system props.

The problem is in the getBoolenProperty() which ignores the first parameter:
=====
!> 211 private static boolean getBooleanProperty(String prop, boolean defaultVal) {
!> 212 String val = System.getProperty("sun.io.useCanonCaches");
    213 if (val == null) return defaultVal;
    214 if (val.equalsIgnoreCase("true")) {
    215 return true;
    216 } else {
    217 return false;
    218 }
    219 }
=====

Looks like a copy-paste bug.
