This isolated example program reproduces the crash seen with HotSpot +
a servlet engine and I have submitted this as a bug to Sun(internal review
ID of: 85224):
public class AdaptiveClassLoader extends ClassLoader
{
protected synchronized Class loadClass(String name, boolean resolve)
throws ClassNotFoundException
{
// The class object that will be returned.
Class c = null;
// Attempt to load the class from the system
try
{
System.out.println("loadSystemClass -> ");
c = loadSystemClass(name, resolve);
System.out.println(c);
if (c != null)
{
if (resolve) resolveClass(c);
return c;
}
}
catch (Exception e)
{
c = null;
}
return c;
}
private Class loadSystemClass(String name, boolean resolve)
throws NoClassDefFoundError, ClassNotFoundException
{
System.out.println("findSystemClass -> ");
Class c = findSystemClass(name);
System.out.println(c);
// Throws if not found.
if (resolve) resolveClass(c);
return c;
}
public static void main(String[] args) throws Exception
{
AdaptiveClassLoader loader = new AdaptiveClassLoader();
Class c = loader.loadClass("[");
c.newInstance();
}
}
