Kenneth Knowles commented on BEAM-11837:
----------------------------------------
Can you try increasing the max JVM heap, or is it already the max the worker VM
can handle?
> Java build flakes: "Memory constraints are impeding performance"

> Java Wordcount Direct Runner (ubuntu-latest) failed a couple times on me with

> should cause the build to fail altogether, so I'm wondering if there's some
> way we can silence this warning.
