Manuel Shenavai created CXF-9091: ------------------------------------ Summary: Camel 3|CXF: ParsingErrors with OneWay Messages Key: CXF-9091 URL: https://issues.apache.org/jira/browse/CXF-9091 Project: CXF Issue Type: Bug Reporter: Manuel Shenavai
Hi everyone, we recently moved from Camel 2 to Camel 3 and we are now observing the following problem with CXF. If a OneWay message exceeds a certain length, the messages fail with a parser error like: Caused by: java.lang.IllegalStateException: Current event not START_ELEMENT or END_ELEMENT at com.ctc.wstx.sr.BasicStreamReader.getNamespaceCount(BasicStreamReader.java:805) ~[woodstox-core-6.2.7.jar:6.2.7] at org.apache.cxf.staxutils.DepthXMLStreamReader.getNamespaceCount(DepthXMLStreamReader.java:122) ~[cxf-core-3.5.2.jar:3.5.2] at org.apache.cxf.staxutils.DepthXMLStreamReader.getNamespaceCount(DepthXMLStreamReader.java:122) ~[cxf-core-3.5.2.jar:3.5.2] at org.apache.camel.component.cxf.converter.DelegatingXMLStreamReader.<init>(DelegatingXMLStreamReader.java:40) ~[camel-cxf-3.17.0.jar:3.17.0] at org.apache.camel.component.cxf.converter.CxfPayloadConverter.convertTo(CxfPayloadConverter.java:225) ~[camel-cxf-3.17.0.jar:3.17.0] at org.apache.camel.component.cxf.converter.CxfPayloadConverterLoader.lambda$registerFallbackConverters$8(CxfPayloadConverterLoader.java:68) ~[camel-cxf-3.17.0.jar:3.17.0] at org.apache.camel.support.SimpleTypeConverter.convertTo(SimpleTypeConverter.java:101) ~[camel-support-3.17.0.jar:3.17.0] ... 30 common frames omitted The error will not happen if we reduce the length of the message or if we change it from OneWay to ResponseReply. This indicates a problem in the async decoupling of the request. During debugging I found that the HTTP thread is used to handle the request. But the actual processing of the message happens in new thread. Maybe the input stream is closed after the http thread is finished (HTTP 202) and the spawned thread cannot read the full content anymore. I created the following reproducer based on Spring Boot: [https://github.com/mash-sap/cxfOneWayError/tree/main] CXF: 3.6.5 Camel CXF: 3.17.0 Tomcat: 9.0.83 -- This message was sent by Atlassian Jira (v8.20.10#820010)
