Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0)
Java HotSpot(TM) Client VM (build 1.3.0, mixed mode)
Subcategory: java-plugin
Applet <param> tags with 8-bit characters have their values sign-extended
when queried from the applet (netscape 4.76, with java-plugin). This is
different from "appletviewer" or "netscape" with netscape's builtin java
implementation (both zero extend 8-bit chars, giving proper unicode encoded
param strings).
Example:
% cat applet.html
<html>
<body>
<applet width="50" height="50" code="applet">
<param name="param1" value="?">
</applet>
</body>
</html>
% cat applet.java
public class applet extends java.applet.Applet {
public void init() {
String param1 = getParameter("param1");
System.out.println("param1=" + param1);
System.out.println("param1[0]=" + (int) param1.charAt(0));
}
}
In appletviewer or with netscape's jvm, this simple applet prints:
param1=?
param1[0]=228
Using the jdk1.3.0 java plug-in from netscape-4.76, this applet prints
param1=?
param1[0]=65508
Note how the param1 parameter was sign-extended (0t228 = 0xe4, 0t65508 = 0xffe4)
