Andreas Veithen resolved AXIOM-517.
-----------------------------------
Resolution: Not A Bug
> Random AXIOM stream errors: Attempted read on closed stream
> -----------------------------------------------------------
>
> Key: AXIOM-517
> URL: https://issues.apache.org/jira/browse/AXIOM-517
> Project: Axiom
> Issue Type: Bug
> Components: API
> Affects Versions: 1.4.0
> Reporter: Mohan Sri
> Priority: Major
> Labels: 1.4.0, AXIOM, AXIS2_1.8.2
> Attachments: TestDetachableInputStream.java
>
>
> While using AXIS 1.8.2 with the dependency of AXIOM 1.4.0, we see random
> stream errors in Prod when under heavy load. This error terminates the AXIS
> request with a fatal error. Here is the trace:
> 2023-03-28 17:20:55,732 (pool-4-thread-5) ERROR [Stub.497]: Error invoking
> query_info: java.io.IOException: {*}Attempted read on closed stream{*}.
> org.apache.axiom.om.OMException: java.io.IOException: Attempted read on
> closed stream.
> at
> org.apache.axiom.om.impl.common.factory.meta.DetachableInputStream.detach({*}DetachableInputStream.java:75{*})
> ~[axiom-1.4.0.jar:1.4.0]
> at
> org.apache.axiom.om.impl.common.builder.OMXMLParserWrapperImpl.detach(OMXMLParserWrapperImpl.java:92)
> ~[axiom-1.4.0.jar:1.4.0]
> at
> org.apache.axis2.kernel.TransportUtils.detachInputStream(TransportUtils.java:578)
> ~[axis2-kernel-1.8.2.jar:1.8.2]
> The issue appears to be that when DetachableInputStream is created, it is
> passed the inputstream it doesn't own. So an external thread could
> potentially close the stream before detach is called on this instance.
> Attached is a driver the generates a stack trace similar to the one we are
> seeing in production. Please run the driver to see the error and then modify
> the driver to have:
> TEST_TYPE testType = DETACH_THEN_CLOSE;
> Recompile and run again to see the issue doesn't happen with this sequence of
> detach and close.
