Hello,

It seems leetcode JVM is not configured properly for concurrency problems.

I try to use ForkJoinPool for https://leetcode.com/problems/web-crawler-multithreaded/ problem

And on this line

ForkJoinPool fjPool = new ForkJoinPool();

I have an exception

java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "modifyThread")
