----------------------------------------
Summary: camel-opa - bound REST response body reading by the
request deadline
Key: CAMEL-26826
URL: https://issues.apache.org/jira/browse/CAMEL-26826
Project: Camel
Issue Type: Bug
Reporter: Andrea Cosentino
Assignee: Andrea Cosentino
h2. Problem / motivation
OpaHttpClient.send uses BodyHandlers.ofInputStream. The response becomes
available before body completion, leaving subsequent SDK body reading outside
the configured request deadline. An isolated Java 21 transport check with a
200ms timeout remained blocked after 800ms when headers and a partial body
arrived promptly.
h2. Proposed scope
Enforce a deadline through complete response consumption and cancel/close
incomplete responses. Keep normal denial, evaluation error and
unavailable-decision handling distinct. Ensure SDK retries do not accidentally
defeat the documented total wait semantics.
h2. Acceptance criteria / validation
* Regression test: headers arrive promptly, body stalls.
* Cover no headers, partial/truncated JSON, interruption and successful
completion.
* Verify the configured deadline and cleanup on the supported JDKs; update
timeout documentation.
h2. References

h2. Context
Follow-up to CAMEL-24784; that resolved ticket introduced transport timeouts,
while this issue covers the remaining body-consumption phase. Not a duplicate
of the original pre-header timeout coverage.
Source: read-only component audit at 5686684cb418. Recheck current main before
implementing; historical references identify the audited code.
