Refactor: Try with Resources

[gr812b]

Current implementation of the analyzers is to open the required readers and writers, perform the operation, then close them. This means that on a crash, the file gets stuck in an inaccessible mode due to the lock. This should be done instead using a try with resources block. Ideally, this does not impact the current error handling method, and simply ensures the writers and readers are closed, while still throwing previous errors. Further, look into patterns that won't be super ugly.
