FULL PRODUCT VERSION :
1.5.0_12

FULL OS VERSION :
Linux RHEL 4

A DESCRIPTION OF THE PROBLEM :
If you run the attached code on 5u12 using the server compiler then it hangs.

The problem appears to be that the inlined call to os::javaTimeMillis() doesn't test for a safepoint condition.

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: No

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile the code and run with the -server VM option.

EXPECTED VERSUS ACTUAL BEHAVIOR :
It should run OK. Instead the jvm hangs (won't respond to CTRL+C or CTRL+\)
REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
public class SafepointFailure extends Thread {
        public void run() {
                while (System.currentTimeMillis() != 1);
        }

        public static void main(String[] args) throws Exception {
                new SafepointFailure().start();
                while (true) {
                        String foo = new String("foo");
                }
        }
}

CUSTOMER SUBMITTED WORKAROUND :
Run with client compiler or disable compilation of the run method.
