bd2019us opened a new pull request #1062: [SECURITY] change Executors.newCachedThreadPool() to newFixedThreadPool(int) URL: https://github.com/apache/brooklyn-server/pull/1062 Since the size of 'sockets' can be large, cached thread pool has a high risk in running out of memory and causes the program crashing. Using newFixedThreadPool() is more secure and should be preferred.
