Summary
HttpResponse construction can throw a RuntimeException. The existing finally block in
HttpRequest.execute() closes the content stream in that case but never calls
LowLevelHttpResponse.disconnect(), leaving the socket open.
Changes
fails; added null-guard and isolated getContent() failures so they don't suppress
the disconnect() call.
Notes
Pre-existing bug, unrelated to the security hardening work (redirect credential stripping,
CRLF validation, XXE hardening) — those are separate PRs.
Fixes #2177 ☕️
