…be executed manually during release preparation due to those tests failing intermittently in CI
Since the default verifier fallback was removed, CLIENT or BOTH policy with a null HostnameVerifier performed no hostname verification at all. ConscryptClientTlsStrategy and the deprecated DefaultClientTlsStrategy constructor now select the BUILTIN policy when no verifier is given, and AbstractClientTlsStrategy rejects CLIENT or BOTH without a verifier.
Once the CONNECT tunnel is established a 407 comes from the origin. It was evaluated against the proxy auth exchange, which failed with a NullPointerException or IllegalStateException. The response is now returned to the caller as is.
The target name was passed as the endpoint name when connecting to the first hop, so the proxy certificate was verified against, and the SNI set to, the target virtual host instead of the proxy. The target name is now used only when upgrading to TLS for the target.
The parser accumulated an unterminated line, or data lines without a blank line, without any limit, so a misbehaving server could exhaust the heap. EventSourceConfig now has maxLineLength (1 MiB) and maxEventSize (8 MiB). When a limit is exceeded the stream fails with MessageConstraintException and its buffers are released.

The parser accumulated an unterminated line, or
data:lines without a blank line, without any limit, so a misbehaving server could exhaust the heap. Reproduced with a single unterminated line:OutOfMemoryErrorafter 64 MiB with-Xmx256m.EventSourceConfignow hasmaxLineLength(1 MiB) andmaxEventSize(8 MiB). When a limit is exceeded the stream fails withMessageConstraintException, reported through the listener failure callback, and its buffers are released. Values <= 0 are rejected.Tests added for both parsers. A failed stream may reconnect under the usual backoff.
