RFR: 7903906: JOL: SA detection code may hang indefinitely

[Aleksey Shipilev]

This is seen when running GHA on macos-aarch64 runners. The attempt to attach to SA would fail cryptically, as waitFor would wait indefinitely for a non-compliant SA to respond. We need to handle waitFor timeouts gracefully.
