It could be made final if moved into the ReflectionData class and
initialized in static initializer of that class. Good idea!
I'll check if this is doable.
Sorry, no go:
// To be able to query system properties as soon as they're available
private static boolean initted = false;
private static void checkInitted() {
if (initted) return;
AccessController.doPrivileged(new PrivilegedAction<Void>() {
public Void run() {
// Tests to ensure the system properties table is fully
// initialized. This is needed because reflection
code is
// called very early in the initialization process
(before
// command-line arguments have been parsed and
therefore
// these user-settable properties installed.) We
assume that
// if System.out is non-null then the System class
has been
// fully initialized and that the bulk of the
startup code
// has been run.
if (System.out == null) {
// java.lang.System not yet fully initialized
return null;
}
String val =
System.getProperty("sun.reflect.noCaches");
if (val != null && val.equals("true")) {
useCaches = false;
}
initted = true;
return null;
}
});
}
