This patch fixes a race condition in KeepAliveProperty test. The client thread could read the `pass` field and fail the test before the server thread had a chance to set the field value to `true`. The fix adds an explicit wait for the server thread to complete.
Without this patch, the failure can be easily reproduced by adding a `Thread.sleep(100);` before `pass = !expectClose;`. ------------- Commit messages: - Wait for server thread Changes: https://git.openjdk.org/jdk/pull/9700/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=9700&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8285836 Stats: 1 line in 1 file changed: 1 ins; 0 del; 0 mod Patch: https://git.openjdk.org/jdk/pull/9700.diff Fetch: git fetch https://git.openjdk.org/jdk pull/9700/head:pull/9700 PR: https://git.openjdk.org/jdk/pull/9700
