with the form

    else
        step += 28;

to work around an apparent JRE bug in which the code always returns 28.

rogerl%netscape.com 7253eff213 Bug #24023, infinite loop in interpreter when catch clause has a throw. 
This was caused by a previous bug fix in which I moved the try stack
decrement to the end of the catch clause because it was getting skipped
by the final statement in the try block (which is always a goto around the
catch block). Better is to make sure the endTry is the statment just before
that goto, and do the try stack decrement in the catch the way god intended.

Hello Norris

In Rhino, the following script gives the error : "function does not always return a value" during the parsing phase. The script
runs perfectly fine in Netscape 4.61. It is an urgent requirement. Many thanks in advance.

Steven

///////////////////////////////////////////////////////SCRIPT  BEGIN  ///////////////////////////////////////////////

a = new test (25);

Yes.  I just did a CVS update to get the latest stuff and we still have
this problem.

I wrote a standalone sample program that duplicates the problem.  Run
JSSupport and you should get this exception:

Norris,

It looks like the classes the optimizer generates call
ScriptRuntime.defineFunction which calls getClassLoader.  This throws a
SecurityException.

We use our own SecuritySupport implementation in Rhino.  This is properly
getting called by the optimizer to generate new classes (e.g.
org.mozilla.javascript.gen.c5 etc.)

However, after defining the class, Codegen.compile calls getClassLoader()
on the new class.  The default SecurityManager doesn't allow
getClassLoader() to be called and so an exception is thrown:

java.lang.RuntimeException: Malformed optimizer package
java.security.AccessControlException: access denied
(java.lang.RuntimePermission getClassLoader )
        at org.mozilla.javascript.optimizer.Codegen.compile(Codegen.java:138)
        at org.mozilla.javascript.Context.compile(Context.java:1761)
        at org.mozilla.javascript.Context.compile(Context.java:1691)
        at org.mozilla.javascript.Context.compileReader(Context.java:810)
        at org.mozilla.javascript.Context.evaluateReader(Context.java:725)
        [...]

This is kind of a pain to duplicate outside of our application, but if you
require a test case I can create one.

Codegen is attempting to call loadClass() after it uses
SecuritySupport.defineClass().  Our SecuritySupport calls loadClass()
internally in its defineClass() implementation.  This is what JavaAdapter
expects.

This is from Codegen.compile():

                         if (securitySupport == null) {
                             if (Context.isSecurityDomainRequired())
                                 throw new SecurityException("Required " +
                                             "security context missing");
                             if (classLoader == null)
                                 classLoader = new JavaScriptClassLoader();
                             clazz = classLoader.defineClass(name, classFile);
                         } else {
                             clazz = securitySupport.defineClass(name,
classFile,
                                                                 securityDom
securityDomain);
                         }
                         ClassLoader loader = clazz.getClassLoader();
                         clazz = loader.loadClass(name);


This is from JavaAdapter.createAdapterClass():


         SecuritySupport ss = cx.getSecuritySupport();
         if (ss != null)  {
             Object securityDomain = cx.getSecurityDomainForStackDepth(-1);
             return ss.defineClass(adapterName, bytes, securityDomain);
         } else {
             if (classLoader == null)
                 classLoader = new MyClassLoader();
             classLoader.defineClass(adapterName, bytes);
             return classLoader.loadClass(adapterName, true);
         }


So JavaAdapter is assuming SecuritySupport.defineClass() will call
ClassLoader.loadClass() on the new class, while Codegen is assuming it
needs to call ClassLoader.loadClass() on the class defined by
SecuritySupport.defineClass().

These should be made consistent, and in both cases it should be assumed
that SecuritySupport will both define and load the class.
