weld-junit5 with Java 17

Is it possible to run weld-junit5 with Java 17? We are using Wildfly 26 with Java 17.

When I run a Unit test I get an exception:

org.jboss.weld.exceptions.WeldException: WELD-001524: Unable to load proxy class for bean Managed Bean [class de.XXX] with qualifiers [@Any @Default] with class class de.XXX using classloader jdk.internal.loader.ClassLoaders$AppClassLoader@2aae9190

I tried to run a JUnit test with weld-junit5 in versions 2.0.2, 3.0.0.Final and 4.0.0.Final and always get above exception.

Solution

  • I solved it by defining the weld-se-core lib for the tests:

    <dependency>
    <groupId>org.jboss.weld.se</groupId>
    <artifactId>weld-se-core</artifactId>
    <version>3.1.9.Final</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.jboss.weld</groupId>
    <artifactId>weld-junit5</artifactId>
    <version>2.0.2.Final</version>
    <scope>test</scope>
</dependency>

    No it is running with Java 17! Also see https://github.com/weld/weld-testing/issues/157 for more details.
