This commit addresses this issue by introducing a fallback for-loop that iterates over the candidate parameters a second time using equality checks instead of identity checks.

Sam Brannen 81fde5ec41 Ensure that MethodParameter.findParameterIndex() is thread-safe

Prior to this commit, parallel invocations of
MethodParameter.findParameterIndex() (invoked indirectly via
SynthesizingMethodParameter.forParameter() and
MethodParameter.forParameter()) could intermittently lead to an
IllegalArgumentException being thrown due to a race condition in the
internal implementation of the JDK's
java.lang.reflect.Executable.getParameters() method.

This commit addresses this issue by introducing a fallback for-loop
that iterates over the candidate parameters a second time using
equality checks instead of identity checks.
