Problem with running simple Java application
In order to speficy my problem #85 , I try running a simple java application, which utlizes Thread.sleep(x).
pulic class TestThread {
public static void main(String args[]) {
try {
System.out.println("Sleep");
Thread.sleep(50);
System.out.println("Woke up");
} catch (InterruptedException e) {
System.out.println("Thread interrupted.");
}
}
}
and my cfg file is same as tests/hooks.cfg except "process" section.
process0 = {
command = "/usr/bin/java TestThread";
}
and executed zsim in java program directory.
$ cd ~/java-test/ # java class files in here
$ ~/zsim/build/opt/zsim ~/zsim/tests/java.cfg
then, following messages are printed.
...
[H] Creating global segment, 1024 MBs
[H] Global segment shmid = 4554753
[H] Deadlock detection ON
[H] Attached to global heap

I also tried sim.pinOption="-smc_strict", but the result was not changed. In ISCA'13 paper, authors report that ZSim supports java workloads. I think some of syscalls/signals are ignored/stolen (by zsim). How to find clear solution for this problem?
PS. I modified java source codes to simplify the problem.
