JDK11, Unable to load source code of com.sun.tools.xjc.runtime.ZeroOneBooleanAdapter as a resource

[vercevales]

Hi!

Having multiple XSD for SAML (official and standard XSDs) and trying to use them to generate classes I got an error: Exception in thread "main" java.lang.InternalError: Unable to load source code of com.sun.tools.xjc.runtime.ZeroOneBooleanAdapter as a resource.

Digging deeper into the issue I have discovered that the missing resources were removed from jaxb-xjc 2.3.2 (which is used in jaxb2-maven-plugin 2.5.0) whereas in jaxb-xjc 2.2.11 (which is used in jaxb2-maven-plugin 2.3.1) they are present.

POM's build section: `

org.springframework.boot spring-boot-maven-plugin org.codehaus.mojo jaxb2-maven-plugin 2.5.0 xjc xjc ${project.basedir}/src/main/resources/ org.apache.maven.plugins maven-compiler-plugin 11 11

</build>`

I have the same problem. I can reproduce both errors (with jaxb2-maven-plugin 2.5.0 and 2.3.1). Are there any known workarounds for this problem yet?

[eriknellessen]

As @vercevales already wrote, the problem is that jaxb-xjc 2.3.2 does not include the missing resources. It seems like this problem has already been fixed in jaxb-xjc in the following commit: https://github.com/eclipse-ee4j/jaxb-ri/commit/0042068395f720bbe368762832e33ede1141f67a

When using jaxb-xjc 2.3.3-b01 (the next version following 2.3.2), I ran into other problems. So I cloned jaxb-xjc, checked out the tag 2.3.2 and cherry-picked commit 0042068395f720bbe368762832e33ede1141f67a. I then installed jaxb-xjc and rebuilt my project. The problem with the missing ZeroOneBooleanAdapter file was gone.

The corresponding issue in the jaxb-ri project is the following: https://github.com/eclipse-ee4j/jaxb-ri/issues/1287
