gcc/java:

2001-04-25  Bryce McKinlay  <bryce@waitaki.otago.ac.nz>

	* decl.c (init_decl_processing): Add new class "protectionDomain"
	field.
	* class.c (make_class_data): Set initial value for "protectionDomain".

libjava:

	java.security merge and ClassLoader compliance fixes.

	* java/lang/Class.h (Class): Include ProtectionDomain.h.
	New protectionDomain field.
	(forName): Add initialize parameter. Fixes declaration to comply with
	JDK spec.
	* java/lang/natClass.cc (forName): Correct declaration of the three-arg
	variant. Honour	"initialize" flag.
	(getProtectionDomain0): New method.
	* java/lang/Class.java: Fix forName() declaration.
	(getPackage): New method based on Classpath implementation.
	(getProtectionDomain0): New native method decl.
	(getProtectionDomain): New method.
	* java/lang/ClassLoader.java (getParent): Now final.
	(definedPackages): New field.
	(getPackage): New.
	(defineClass): New variant with protectionDomain argument.
	(definePackage): New.
	(getPackages): New.
	(findSystemClass): Now final.
	(getSystemResourceAsStream): Remove redundant "final" modifier.
	(getSystemResource): Remove redundant "final" modifier.
	(getResources): Now final.
	(protectionDomainPermission): New static field.
	(unknownProtectionDomain): Ditto.
	(defaultProtectionDomain): Ditto.
	(getSystemClassLoader): Now non-native.
	* java/util/ResourceBundle.java (tryGetSomeBundle): Use the correct
	arguments for Class.forName().
	* java/lang/Package.java: New file.
	* gnu/gcj/runtime/VMClassLoader.java (getVMClassLoader): Removed.
	(instance): Static initialize singleton.
	(findClass): Override this, not findSystemClass.
	* java/lang/natClassLoader.cc (defineClass0): Set class's
	protectionDomain field as specified.
	(getSystemClassLoader): Removed.
	(findClass): Renamed from findSystemClass. Call the interpreter via
	URLClassLoader.findClass if loading class via dlopen fails.

	* java/security/*.java: java.security import/merge with Classpath.
	* java/security/acl/*.java: Likewise.
	* java/security/interfaces/*.java: Likewise.
	* java/security/spec/*.java: Likewise.
	* java/net/NetPermission.java: Likewise.
	* java/net/SocketPermission.java: Likewise.
	* gnu/java/security/provider/DefaultPolicy.java: Likewise.

The Identity class is used to repsent people and companies that
can be authenticated using public key encryption. The identities
can also be abstract objects such as smart cards.
Identity object store a name and public key for each identity.
The names cannot be changed and the identities can be scoped.
Each identity (name and public key) within a scope is unique
to that scope.
Each identity has a set of ceritificates which all specify the
same public key but not necessarily the same name.
The Identity class can be subclassed to allow additional
information to be attached to it.

@deprecated Use java.security.KeyStore, the java.security.cert
package, and java.security.Principal.
