yes i did:
public class test3 {
static int i;
static Exception e = new Exception("");
public static void main(String[] args) {
for( int i = 0; i < 500; i++ ) {
try {
a();
Did you catch it?

Chris,
The "Micro performance benchmarking" using Java is danger, because of
JIT's optimization may "overwhelm any detectable differences in
underlying performance"[1], so I agree with you that the example

Agreed. I think the solution in the JIRA I submitted has a reasonable
balance of being helpful while not being significantly slower than the
original.

Etienne,
It would be great to see SableVM fully embrace Harmony Class Libs.
Excellent approach!
The original design goal for kernel_path, the port of Harmony Class
Libs to JCHEVM/SableVM, was to make absolutely minimal changes to the
JVM. By design, this port uses little, if any, of the Harmony
As we discussed earlier we fight for performance not only in case of
'positive' behavior but also when methods throw exceptions.
Throwing exceptions with predefeined constant message is much
faster then with string concatenation.
Thanks,
Mikhail
