When nodes in the ConcurrentHashTable get corrupted and their hash codes don't match, resizing fails with an unhelpful message - this change makes the error clearer and adds a test to confirm this. Ran GHA Sanity Checks, and local Tier 1, and Tier 2 tests. Patch is clean.

Yes, that's correct, it'd be part of tier1 ([example](https://github.com/satyenme/jdk21u-dev/actions/runs/13864297548/job/38802403056#step:9:4513))
