How can I handle StackOverflowError in Java?
667
StackOverflowError is an error which Java doesn't allow to catch, for instance, stack running out of space, as it's one of the most common runtime errors one can encounter.
Stack overflow means, that you have no room to store local variables and return adresses. If your jvm does some form of compiling, you have the stackoverflow in the jvm as well and that means, you can't handle it or catch it.
One method to prevent stack overflow is to track the stack pointer with test and measurement methods. Use timer interrupts that periodically check the location of the stack pointer, record the largest value, and watch that it does not grow beyond that value.
I'm not sure what you mean with "handle".
You can certainly catch that error:
public class Example {
public static void endless() {
endless();
}
public static void main(String args[]) {
try {
endless();
} catch(StackOverflowError t) {
// more general: catch(Error t)
// anything: catch(Throwable t)
System.out.println("Caught "+t);
t.printStackTrace();
}
System.out.println("After the error...");
}
}
but that is most likely a bad idea, unless you know exactly what you are doing.
