Normal, streaming, and resume requests now return specific construction errors and release allocated JNI references when construction fails. ChangesJNI request construction
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR prevents incomplete Android requests from reaching the transport and reports allocation failures as out-of-memory errors, avoiding bodyless requests or misleading network errors. It is otherwise mergeable with owner awareness that one repository coding-rule violation in the touched JNI file still needs follow-up.

every conversion used to create or populate j_body, including the additional
request-body handling sites. Reject oversized lengths with the established
invalid-argument error, not RAC_ERROR_OUT_OF_MEMORY, and preserve the existing
cleanup behavior.

Replace direct JNI string literals with structured values.
Line 201 passes "java/lang/String" directly to FindClass. Lines 217 and 225 also use direct empty-string fallback values. Use the project structured JNI values for these contracts.
As per coding guidelines: “Always make sure that you're using structured types, never use strings directly so that we can keep things consistent and scalable and not make mistakes.”
Also applies to: 217-225

Description
The OkHttp transport adapter's request entry points (
okhttp_request_send,okhttp_request_stream,okhttp_request_resume) marshaled the method, URL, and body into JVM objects without checking the results:NewStringUTF(req->method)/NewStringUTF(req->url)returningNULLwere passed straight intoCallStaticObjectMethod, so a failed allocation surfaced later as a thrown exception translated into a genericRAC_ERROR_NETWORK_ERROR.NewByteArray()leftj_body == nullptrand execution continued, invoking the transport without the body that commons supplied (a POST/PUT can ship bodyless) — or, if the OOM exception was still pending, producing a generic network error.All three entry points now reject incomplete marshaling consistently: if either the method or URL string cannot be created, or
NewByteArrayfails while a non-empty body is required, the pending JNI exception is cleared, the created local references are released, andRAC_ERROR_OUT_OF_MEMORYis returned before the Kotlin side is invoked. TheSetByteArrayRegionfill and all other behavior are unchanged.Type of Change
