Describe the bug
We are upgrading our library dependency from 15.0 to 16.1 recently and found that DataFetchingFieldSelectionSet updated at #2079 has a regression in performance making our HTTP request 10+ times longer.
We use Java Flight Recorder to narrow down the root cause and found that it is because the HashMap.resize() in NormalizedQueryTreeFactory.createNormalizedQueryImpl.
Below screenshots show that the normalizedFieldToMergedField has 1.29 M entries and other local variables here also extremely large in size.
To Reproduce
Please provide a code example or even better a test to reproduce the bug.
