io.netty.handler.codec.DecoderException: io.netty.util.IllegalReferenceCountException: refCnt: 0

[jonbuck16]

Hi,

I am getting the following exception when trying to push an application into my local pcfdev instance.. The same project and application works when using version 1.1.3 of the java client..

Any ideas? can't find any reference to this exception on the internet...

Push Code...

Path applicationFilePath = Paths.get(applicationFile.toURI());

 PushApplicationRequest request = PushApplicationRequest.builder()
                    .application(applicationFilePath)
                    .buildpack(getBuildpackValue(manifest))
                    .command(getCommandValue(manifest))
                    .diskQuota(getDiskQuotaValue(manifest))
                    .host(alias.asFull())
                    .instances(getApplicationInstances(manifest))
                    .memory(getMemoryValue(manifest))
                    .name(alias.fullName())
                    .noStart(true)
                    .stack(getStackValue(manifest))
                    .stagingTimeout(Duration.ofMinutes(5))
                    .startupTimeout(Duration.ofMinutes(5))
                    .build();

            operations.applications().push(request).doOnSuccess(aVoid -> log.INFO("Application pushed")).block(Duration.ofMillis(300000));

Stack Trace...

Which version of the client and dependencies are you using?

[jonbuck16]

I am using 2.9.0, the only other change I had to make was to up the version of Jackson core to 2.8.7.. I can post a full list if required..

[nebhale]

I'm just interested in the four main versions described in the documentation.

[jonbuck16]

Yes my decencies match those versions..

[jonbuck16]

Dependencies sorry

[nebhale]

Can you please do a run of your application with cloudfoundry-client log set to DEBUG? This will allow me to see exactly where in the execution this is happening.
