Autofuzz can stall indefinitely when constructing arguments via BigInteger(int, int, Random), which searches for a random prime with up to Integer.MAX_VALUE bits. Introduce a denylist of constructors that are never considered during constructor discovery and add this constructor to it. Fixes CodeIntelligenceTesting#1055

Fixes #1055
In autofuzz mode, constructor discovery can pick
BigInteger(int, int, Random), which searches for a random prime with the given bit length and can take practically forever for large arguments, stalling the fuzzer.This adds a denylist of constructors that are never considered during constructor discovery in
AccessibleObjectLookupand putsBigInteger(int, int, Random)on it, as suggested in the issue. The denylist is a simple static set for now, so further problematic constructors can easily be added; making it user-configurable could be a follow-up if needed.Includes a unit test verifying that the denylisted constructor is filtered out while other
BigIntegerconstructors remain available.
