Deadlock on terminating launch #2460
Description
While checking things for #2283, I wanted to terminate a launch before it was done.
That lead to a deadlock:
"main" #1 [129185] prio=6 os_prio=0 cpu=24055.55ms elapsed=290.14s tid=0x00007fc5cc01bb70 nid=129185 waiting for monitor entry [0x00007fc5d2dfd000]

Snippet is:
public class TestConsoleHang {
public static void main(String[] args) {
int N = 1_000_000;
int M = 100;
byte[] b = new byte[N];
for (int i = 0; i < N; ++i) {
b[i] = (byte) (49 + (i % 9));
}
String s = new String(b);
for (int i = 0; i < M; ++i) {
System.out.println(s);
}
}
}
I ran this, clicked on the terminate button in the Console view and Eclipse hanged.
