Possible memory leak with latest release 1.0.9

[abhansh-highlevel]

We recently upgraded our authorizenet package from 1.0.8 to 1.0.9 due to getting empty undefined response in certain scenarios while attempting to charge a card.
Since we've updated the package we are having a memory leak in our services, where we are seeing a constant increase in memory until the service reaches the memory limit and crashes.

We performed load testing on both Version 1.0.8 and Version 1.0.9 with 2,000 requests in a 5-minute span. The API tested was APIControllers.CreateTransactionController(createRequest.getJSON()) and below are the results

Base memory - 300MB

• Version 1.0.9 - Initially, the memory usage spiked from 300MB to 1.4GB while processing the 2000 requests. After processing all the requests, the memory remained at 1.4GB and did not go down

• Version 1.0.8 : Initially, the memory usage spiked from 300MB to 450MB while processing the 2000 requests. Once the requests were processed, the memory came down to 300MB

• The first two lines in the below graph indicates the memory usage in 1.0.9 and the last line in the graph indicates the memory usage in version 1.0.8
