The pattern is too broad and it is catching failures in System.Text.Json not ArrayPool tests. I'm going to close the issue, feel free to update the pattern to match the ArrayPool tests

[lewing]

Updating the condition and reopening

[lewing]

@kg here are some common arraypool failures

Also worth reading #853

I guess other places don't produce as nice message when they can't allocate
