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.
