Exception Provider class xmlpull not found in modularized application

[tobiasdiez]

When using applicationinsights-core-2.5.1 in an modularized java 12 (or 13) application, you get the following error:

Error:java: java.lang.module.FindException: Unable to derive module descriptor for applicationinsights-core-2.5.1.jar
Provider class com.microsoft.applicationinsights.core.dependencies.xmlpull.mxp1.MXParser,org.xmlpull.mxp1_serializer.MXSerializer not in module

The file /META-INF/services/com.microsoft.applicationinsights.core.dependencies.xmlpull.v1.XmlPullParserFactory indeed contains com.microsoft.applicationinsights.core.dependencies.xmlpull.mxp1.MXParser,org.xmlpull.mxp1_serializer.MXSerializer which is indeed a strange format (as there should be one class per line). I guess one should use StAX instead of XPP3 anyway...

Hi @tobiasdiez, thanks for reporting this! I wonder if the problem is that org.xmlpull.mxp1_serializer.MXSerializer should be shaded.

Can you try modifying /META-INF/services/com.microsoft.applicationinsights.core.dependencies.xmlpull.v1.XmlPullParserFactory to instead contain

com.microsoft.applicationinsights.core.dependencies.xmlpull.mxp1.MXParser,com.microsoft.applicationinsights.core.dependencies.xmlpull.mxp1_serializer.MXSerializer

and see if that change would fix the issue?

In 2.6.1 it is still present: JabRef/jabref#6594

Hi @tobiasdiez, can you create a github repository with a simple repro?

Hello. I am facing the same problem.
Here's a simple test.
https://github.com/jesjobom/applicationinsights-java-module-test

module-info.java

module com.jesjobom {
    requires applicationinsights.core; //automatic module
}

Error:

Caused by: java.lang.module.InvalidModuleDescriptorException: Provider class com.microsoft.applicationinsights.core.dependencies.xmlpull.mxp1.MXParser,org.xmlpull.mxp1_serializer.MXSerializer not in module
