Encountering MappableException after upgrading helidon and jersey

Question

After upgrading helidon to 2.5.4 and jersey to 2.35, I am getting the following exception in one of the API. With previous version of helidon(2.0.2) and jersey(2.29.1), it used to work fine. Can you please help to resolve this issue.

{"level":"ERROR","logger":"org.glassfish.jersey.server.ServerRuntime$Responder","thread":"jersey-thread-7","ts":1671639547627,"x-request-id":"","msg":"An I/O error has occurred while writing a response message entity to the container output stream.:\norg.glassfish.jersey.server.internal.process.MappableException: java.io.IOException: Bad news: the stream has been closed\n\tat org.glassfish.jersey.server.internal.MappableExceptionWrapperInterceptor.aroundWriteTo(MappableExceptionWrapperInterceptor.java:67)\n\tat org.glassfish.jersey.message.internal.WriterInterceptorExecutor.proceed(WriterInterceptorExecutor.java:139)\n\tat org.glassfish.jersey.message.internal.MessageBodyFactory.writeTo(MessageBodyFactory.java:1116)\n\tat org.glassfish.jersey.server.ServerRuntime$Responder.writeResponse(ServerRuntime.java:635)\n\tat org.glassfish.jersey.server.ServerRuntime$Responder.processResponse(ServerRuntime.java:373)\n\tat org.glassfish.jersey.server.ServerRuntime$Responder.process(ServerRuntime.java:363)\n\tat org.glassfish.jersey.server.ServerRuntime$1.run(ServerRuntime.java:258)\n\tat org.glassfish.jersey.internal.Errors$1.call(Errors.java:248)\n\tat org.glassfish.jersey.internal.Errors$1.call(Errors.java:244)\n\tat org.glassfish.jersey.internal.Errors.process(Errors.java:292)\n\tat org.glassfish.jersey.internal.Errors.process(Errors.java:274)\n\tat org.glassfish.jersey.internal.Errors.process(Errors.java:244)\n\tat org.glassfish.jersey.process.internal.RequestScope.runInScope(RequestScope.java:265)\n\tat org.glassfish.jersey.server.ServerRuntime.process(ServerRuntime.java:234)\n\tat org.glassfish.jersey.server.ApplicationHandler.handle(ApplicationHandler.java:684)\n\tat io.helidon.webserver.jersey.JerseySupport$JerseyHandler.lambda$doAccept$4(JerseySupport.java:335)\n\tat io.helidon.common.context.Contexts.runInContext(Contexts.java:117)\n\tat io.helidon.common.context.ContextAwareExecutorImpl.lambda$wrap$7(ContextAwareExecutorImpl.java:154)\n\tat java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128)\n\tat java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628)\n\tat java.base/java.lang.Thread.run(Thread.java:834)\nCaused by: java.io.IOException: Bad news: the stream has been closed\n\tat io.helidon.webserver.jersey.ResponseWriter$DataChunkOutputStream.awaitRequest(ResponseWriter.java:327)\n\tat io.helidon.webserver.jersey.ResponseWriter$DataChunkOutputStream.write(ResponseWriter.java:186)\n\tat org.glassfish.jersey.message.internal.CommittingOutputStream.write(CommittingOutputStream.java:200)\n\tat org.glassfish.jersey.message.internal.WriterInterceptorExecutor$UnCloseableOutputStream.write(WriterInterceptorExecutor.java:276)\n\tat com.fasterxml.jackson.core.json.UTF8JsonGenerator._flushBuffer(UTF8JsonGenerator.java:2171)\n\tat com.fasterxml.jackson.core.json.UTF8JsonGenerator._writeBytes(UTF8JsonGenerator.java:1260)\n\tat com.fasterxml.jackson.core.json.UTF8JsonGenerator.writeFieldName(UTF8JsonGenerator.java:284)\n\tat com.fasterxml.jackson.databind.ser.BeanPropertyWriter.serializeAsField(BeanPropertyWriter.java:726)\n\tat com.fasterxml.jackson.databind.ser.std.BeanSerializerBase.serializeFields(BeanSerializerBase.java:774)\n\tat com.fasterxml.jackson.databind.ser.BeanSerializer.serialize(BeanSerializer.java:178)

I also see the below warning whenever the mappableexception is encountered.

{"level":"WARN","logger":"io.helidon.webserver.BareResponseImpl","thread":"jersey-thread-1","ts":1671689369384,"x-request-id":"","msg":"Entity was requested and not fully consumed before a response is sent.

Below is the signature of the api which errored,

    @post
    @path("test")
    @produces(MediaType.APPLICATION_JSON + "; charset=UTF-8")
    @consumes(MediaType.APPLICATION_JSON + "; charset=UTF-8")
    @timed(name="app_kpi",
    absolute = true,
    reusable = true,
    unit=MetricUnits.NANOSECONDS,displayName="test",
    tags = {"api=test"})
    @tag(name = "Version2")
    @APIResponse(responseCode = "200", description = "Success", content = @content(schema = @Schema(type=SchemaType.ARRAY, implementation = OutputRecord.class)))
    @APIResponse(responseCode = "403", description = "Forbidden")
    @APIResponse(responseCode = "401", description = "Unauthorized")
    @APIResponse(responseCode = "500", description = "An unexpected error occurred during the request.")
    @authenticated

    content = @content(schema = @Schema(type = SchemaType.ARRAY, implementation = InputRecord.class))) Vector <InputRecords> inputRecords)
