This issue is a regression from 7e48413eb0 8285881: Update WebKit to 614.1. For synchronous requests, we have an additional buffer to collect data, and the appending data into this buffer is doing in a wrong way: we use Vector::append(U&& u), which adds only the first data element. Instead, we should use Vector::append(const U* u, size_t size) in order to add all obtained data.
I have added the test for this issue to LoadTest.java ------------- Commit messages: - 8311097: Synchron XMLHttpRequest not receiving data Changes: https://git.openjdk.org/jfx/pull/1227/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1227&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8311097 Stats: 52 lines in 4 files changed: 50 ins; 1 del; 1 mod Patch: https://git.openjdk.org/jfx/pull/1227.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1227/head:pull/1227 PR: https://git.openjdk.org/jfx/pull/1227
