Browse source 
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.
