The following program produces incorrect results -

class test2
{
    static public void main(String args[])
    {
        new test2();
    }

    test2()
    {
        Object cols[] = { null, null, null, null, null, null, null, null};

int i = 0;
int j = 0;
int k = 0;

        for (k=0; k<10; k++) {
for (i=0; i<11; i++)
for (j=0; j<12; j++)
try {
drawImage(i,j,k,cols[k%8]);
} catch(Throwable e) {
System.out.println("k="+k + " i="+i + " j="+j + "e="+e);
return;
}
}
    }

    private void drawImage(int i,int j,int k,Object c)
    {
if (k == 1 && i == 2 && j == 3)
throw new java.lang.Error("I'm an Error");
    }
}

Result with the JIT -

Symantec Java! JustInTime Compiler Version 3.00.066(x) for JDK 1.2
Copyright (C) 1996-98 Symantec Corporation

k=81653608 i=2 j=3 e=java.lang.Error: I'm an Error
^^^^^^^^^^

Without the JIT, the result is ok:

k=1 i=2 j=3 e=java.lang.Error: I'm an Error
