Loader constraint violation: javax.xml.soap.SOAPFault
Hello,
I'm getting LinkageError when processing SOAPFault:
java.lang.LinkageError: loader constraint violation: loader (instance of
<bootloader>) previously initiated loading for a different type with name
"javax/xml/soap/SOAPFault"
I've found out the very old issue about this:
https://issues.apache.org/jira/browse/KARAF-1840
Is it possible that it came back? Or this is my configuration error?
I'm using karaf 4.2.4 with apache-cxf 3.3.1, on JDK8.
I've configured everything with karaf 4.1.3 and definitely my code wasn't
running without providing apache-cxf. After updating to 4.2.4 I've got only
to upgrade cxf version.
I've got 'luck' with not getting SAOPFaults from remote server, at least
nobody noticed that problem after upgrade...
Can it be some issue between karaf and cxf?
And general question: how to debug such issues in first line? The class is
allegedly loaded twice, but which bundles have loaded it using which
classloaders?

I see only one exporter of javax.xml.soap:
Bundle 353 - Apache ServiceMix :: Specs :: SAAJ API 1.3 2.9.0 (state:
Active)
Symbolic Name: org.apache.servicemix.specs.saaj-api-1.3
Version: 2.9.0
Bundle Location:
mvn:org.apache.servicemix.specs/org.apache.servicemix.specs.saaj-api-1.3/2.9.0
Last Modification: Mon Jun 03 15:16:00 CEST 2019
Bundle Documentation: http://www.apache.org/
Vendor: The Apache Software Foundation
Description: This pom provides project information that is common to all
ServiceMix branches.
Start Level: 10
Exported Packages:
javax.xml.soap,version=1.3.0
Is it possible that someone has loaded that package from JRE, and not
endorsed version? Unfortunately my knowledge to endorsed mechanism is very
rudimentary, and java.lang.LinkageError is something that I wasn't even
familiar with until now.

I can provide more specific information. I've checked other web services that
we are calling.
The services that throws declared exception (via wsdl:fault section in wsdl)
are OK.
The only problem are services that declare no exceptions, and throw runtime
exceptions. Those exceptions are tried to be mapped to SOAPFault in CXF
code, and this is what is failing.
So the problem might never arise in properly defined web service
environment, where all exceptions that are thrown are declared in WSDL.
I hope this will be helpful in localizing the issue. I can imagine that case
wasn't tested because it's quite specific (unfortunately, if you're forced
to cooperate with 3rd party infrastructure, you can't influence the way they
(mis)behave).

Hello,
I've found something out.
The exception comes from:
java.lang.LinkageError: javax/xml/soap/SOAPFault
at javax.xml.ws.soap.SOAPFaultException.<init>(SOAPFaultException.java:63)
~[?:?]
at
org.apache.cxf.jaxws.JaxWsClientProxy.mapException(JaxWsClientProxy.java:195)
~[?:?]
at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:145)
~[?:?]
The class javax.xml.ws.soap.SOAPFaultException comes from system bundle (0),
which means, it has loaded javax.xml.soap.SOAPFault from JRE.
However, system bundle doesn't export javax.xml.soap package, it comes (in
my case) from org.apache.servicemix.specs.saaj-api-1.3
If I understand it correctly, the proxy generated by CXF, called from my
module, with my module's class loader, has loaded javax.xml.soap.SOAPFault
definition from org.apache.servicemix.specs.saaj-api-1.3, while
javax.xml.ws.soap.SOAPFaultException is bound with class definition loaded
from JRE, which generates LinkageError.
Could you check if it is plausible, and what is the possible workaround?

I gonna check and try to reproduce on the Karaf SOAP provided example:

I've updated karaf to version 4.2.5 and cxf to 3.3.2 and the problem is still
existing.
Only handlin of SOAPFault produces the problem.
How exactly are you using CXF?
I have the following import in my bundle: org.apache.cxf.jaxws.spi
If I remove it, I have the following error:
SEVERE: Unknown JAXBContext implementation: class

Hi,
did you check that you don't have dual bundle version ?
Can you check with package:exports the bundles providing javax.xml.soap
package ?
FYI, we are using Karaf 4.2.5 with CXF 3.3.2 without problem. Anyway,
let me test on the Karaf SOAP example.
Regards
