Please review this fix for an intermittent test failure. On some configurations, the default `expect` timeout of 10 seconds is insufficient. It is increased to 20; it's hard to imagine a configuration for which that new value would still be insufficient, but we'll see.
Aside from that, test-generated diagnostics are improved: the version of the `expect` command and the duration of each test method are recorded. `output.exp` is modified for robustness and clear indication of the timeout condition. I was reminded, out-of-band, that test timeouts should be scaled with `test.timeout.factor`. I propose to integrate this PR first and then separately update all the affected tests to scale their `expect` timeouts. ------------- Commit messages: - Initial commit Changes: https://git.openjdk.org/jdk/pull/19627/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=19627&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8333358 Stats: 68 lines in 3 files changed: 62 ins; 2 del; 4 mod Patch: https://git.openjdk.org/jdk/pull/19627.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/19627/head:pull/19627 PR: https://git.openjdk.org/jdk/pull/19627
