This PR fixes intermittent test failures. The test was broken by 95ca94436d12974d98b1b999f9cc8408d64cbe3c, which changed the `/firstCall` handler to return chunked response (second parameter to `sendResponseHeaders` was `0`). The test verifies the behavior of KeepAliveStreamCleaner, which only works on responses containing `Content-Length` header, and sometimes fails on chunked streams.
Additionally I removed the unnecessary byte-to-character-to-byte conversion introduced in the same commit. No failures after 50 test runs. Without the change the test failed 3 times in 10. ------------- Commit messages: - Fix test Changes: https://git.openjdk.org/jdk/pull/13194/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=13194&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8304962 Stats: 8 lines in 1 file changed: 0 ins; 2 del; 6 mod Patch: https://git.openjdk.org/jdk/pull/13194.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/13194/head:pull/13194 PR: https://git.openjdk.org/jdk/pull/13194
