OutOfMemoryError isn’t a memory problem.
It’s a reference problem.
Objects stay alive because references stay alive.
GC can’t free what’s still reachable.

I always wondered, if BigDecimal.toPlainString() is a DoS attack surface.

Try Fail.java:

import java.math.BigDecimal;
public class Fail {
public static void main(String[] argv) throws Exception {
new BigDecimal("1e" + (Integer.MAX_VALUE-100)).toPlainString();
}
}

and run it with

java -Xmx4g Fail.java

Fails with
java.lang.OutOfMemoryError: Java heap space
meaning any server using BigDecimal.toPlainString() on user input may just crash.
