Subject: ObjectInputStream.java: Made all calls to dumpElement[ln] conditional
 on dump flag.

2004-02-06  Jeroen Frijters  <jeroen@frijters.net>

	* java/io/ObjectInputStream.java: Made all calls
	to dumpElement[ln] conditional on dump flag. (readObject): Changed to
	use cached info from ObjectStreamClass. (readClassDescriptor):
	Cache more information in ObjectStreamClass. (processResolution,
	readFields): Use cached info from ObjectStreamClass.
	(newObject): Throw exception instead of returning null for failure.
	(getField, getMethod, callReadMethod, setBooleanField, setByteField,
	setCharField, setDoubleField, setFloatField, setIntField,
	setLongField, setShortField, setObjectField, readObjectParams):
	Removed. (dumpElement, dumpElementln): Removed dump flag condition
	check.
	* java/io/ObjectStreamField.java (hasReadMethod): Removed.
	(setClass): Added call to cacheMethods() (findMethod): New method.
	(cacheMethods): New method. (ObjectStreamClass): Added call to
	cacheMethods(). (setFields): Cache fields. (getClassUID): Use
	AccessController.doPrivileged to invoke setAccessible.
	(readObjectMethod, readResolveMethod, realClassIsSerializable,
	realClassIsExternalizable, fieldMapping, firstNonSerializableParent):
	New fields.
	* java/io/ObjectStreamField.java (ObjectStreamField): New constructor.
	(ObjectStreamField): Removed FIXME workaround. (getTypeString,
	isPrimitive): Made safe for cases where type == null.
	(setBooleanField, setByteField, setCharField, setShortField,
	setIntField, setLongField, setFloatField, setDoubleField,
	setObjectField): New methods.
