Tomcat 4.0.1 doing odd Exception handling

[Rob Johnson <ro...@rsjohnson.fsnet.co.uk>]

I'm having an interesting problem with Tomcat 4.0.1:

I run this line of code from within a servlet:

try {
    System.out.println("1");
    Classloader.getSystemClassLoader().loadClass(classname);
    System.out.println("2");
} catch (Exception e) {
    System.out.println("Executing catch block");
} finally {
    System.out.println("Executing finally block");
}

The Classloader line of code causes some sort of error because '2' is never
printed out, but the catch block isn't executed either - execution jumps
straight to the
finally block. I can't find anything unusual in the logs.  Can anyone help?

The test code works fine with Tomcat 3.

If an Error is thrown, the catch (Exception) wont catch it.  If all you
want to do is find out what is going on, then you could change the catch
(Exception) to catch (Throwable) and you should see something.  *warning*
this is about the only thing worse than catch (Exception) imho, so dont
leave it in your code once your figured it out (o:
