Description
Hi. I'm using Spring Boot (2.2.4.RELEASE) with Camel (3.1.0) and I've come across the following error. I should note that i'm having a hard time reproducing this issue.
*************************** APPLICATION FAILED TO START *************************** Description: An attempt was made to call a method that does not exist. The attempt was made from the following location: com.ctc.wstx.evt.CompactStartElement.getAttributes(CompactStartElement.java:94) The following method did not exist: 'org.codehaus.stax2.ri.EmptyIterator org.codehaus.stax2.ri.EmptyIterator.getInstance()' The method's class, org.codehaus.stax2.ri.EmptyIterator, is available from the following locations: jar:file:/app/libs/stax2-api-4.2.jar!/org/codehaus/stax2/ri/EmptyIterator.class It was loaded from the following location: file:/app/libs/stax2-api-4.2.jar Action: Correct the classpath of your application so that it contains a single, compatible version of org.codehaus.stax2.ri.EmptyIterator
I was wondering if this is related to the fact that camel-jacksonxml introduces both org.codehaus.woodstox:woodstox-core-asl:jar:4.4.1 and com.fasterxml.woodstox:woodstox-core:jar:6.0.3 on the classpath , as seen below.
INFO] +- org.apache.camel.springboot:camel-jacksonxml-starter:jar:3.1.0:compile [INFO] | \- org.apache.camel:camel-jacksonxml:jar:3.1.0:compile [INFO] | +- org.apache.camel:camel-support:jar:3.1.0:compile [INFO] | +- com.fasterxml.jackson.dataformat:jackson-dataformat-xml:jar:2.10.2:compile [INFO] | | +- org.codehaus.woodstox:stax2-api:jar:4.2:compile [INFO] | | \- com.fasterxml.woodstox:woodstox-core:jar:6.0.3:compile [INFO] | +- com.fasterxml.jackson.module:jackson-module-jaxb-annotations:jar:2.10.2:compile [INFO] | \- org.codehaus.woodstox:woodstox-core-asl:jar:4.4.1:compile
It's unclear to me why camel-jacksonxml has a dependency on woodstox-core-asl while woodstox-core is already available, albeit transitively.
