Hi,
I try to use jdk15+libthr on 6.0 and CURRENT, somtimes jdk15 could not
pass very simple Test:
# cat TestThread.java
public class TestThread extends Thread{
public TestThread() {
}
public void run() {
try{
Thread.sleep(12);
//Thread.sleep(1235);
}
catch(Exception ex) {
}
System.out.println("end");
}
public static void main(String[] args) throws Exception {
TestThread[] threads = new TestThread[5000];
for(int i=0;i<threads.length; i++) {
threads[i] = new TestThread();
try{
Thread.sleep(50);
}
catch(Exception ex) {
}
threads[i].start();
threads[i].join();
}
}
}
