Bryce McKinlay 28f7d9d05a decl.c (init_decl_processing): Add new class "protectionDomain" field.
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:

2001-04-25  Bryce McKinlay  <bryce@albatross.co.nz>

	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.

	* Makefile.am: Add new classes.
	* Makefile.in: Rebuilt.
	* gcj/javaprims.h: CNI namespace rebuild.

/**
KeyFactorySpi is the Service Provider Interface (SPI) for the
KeyFactory class. This is the interface for providers to
supply to implement a key factory for an algorithm.
Key factories are used to convert keys (opaque cryptographic
keys of type Key) into key specifications (transparent
representations of the underlying key material).
Key factories are bi-directional. They allow a key class
to be converted into a key specification (key material) and
back again.
For example DSA public keys can be specified as
DSAPublicKeySpec or X509EncodedKeySpec. The key factory
translate these key specifications.
