ClassLoader ctxLoader = null;
try {
    ctxLoader = Thread.currentThread().getContextClassLoader();
    return Class.forName(name, true, ctxLoader);
} catch (ClassNotFoundException ex) {
} catch (SecurityException ex) {
return Class.forName(name);

case "short":
    return short.class;
case "int":
    return int.class;
case "long":
...
ClassforName(String name, Class caller)
for Name 
ClassLoader threadClassLoader = Thread.currentThread().getContextClassLoader();
if (threadClassLoader != null) {
    try {
        return Class.forName(name, true, threadClassLoader);
    } catch (ClassNotFoundException cnfe) {
        if (cnfe.getException() != null) {
            throw cnfe;
ClassLoader callerClassLoader = caller.getClassLoader();
if (callerClassLoader != null) {
    try {
        return Class.forName(name, true, callerClassLoader);
    } catch (final ClassNotFoundException cnfe) {

return classes;
ClassforNameElseNull(final String fullName)
