There is OOM an attempt to allocate ~1G bytes object:

If it is intentional, so test should expect heap (Tenure really) is almost empty.

The test is allocating memory until an OOM occurs.

The test failed because it timed out, not because of the intentional OOMs. There is no indication or diagnostics to show what it was doing when it timed out. Given we couldn't reproduce it, we couldn't be overly concerned.
