Unable to import Java classes: Illegal char<:> at index 4

Describe the Bug

I am unable to import java classes. When typing the name of the class in the search box, no class appear. In Developer tools I see following error:

dmn-loader.js:2 Error: Illegal char <:> at index 4: file://D:\src\drools\kogito-examples\kogito-quarkus-examples\dmn-quarkus-example\src\main\java\com\mc\Activator.java
    at e.callback (DmnEditorEnvelopeApp.js:2:517048)
    at e.receive (DmnEditorEnvelopeApp.js:2:518804)
    at Object.receive (DmnEditorEnvelopeApp.js:2:514121)
    at e.receive (DmnEditorEnvelopeApp.js:2:521333)
    at eventListener.eventListener (DmnEditorEnvelopeApp.js:2:520493)

I was following this blog post entry https://blog.kie.org/2022/05/dmn-types-from-java-classes.html. I tried creating my own project and also cloned examples repository. Same issue on both.

Steps to Reproduce

1. open https://github.com/kiegroup/kogito-examples/tree/stable/kogito-quarkus-examples/dmn-quarkus-example in VS Code
2. create Activator class:

package com;

import org.kie.api.project.KieActivator;

@KieActivator
public class Activator {
    
}

1. create java bean:

package com;

public class Person {
    String firstName;
    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
}

1. Open Traffic Violation.dmn and try to search the Person class
2. In Developer tools Error: Illegal char <:> at index 4: error appears.

Expected Behavior

Plugin should be able to fetch my model classes.

Environment

• OS: Windows
• Visual Studio Code version: 1.71.2
• DMN Editor plugin: 0.23.0
• Language Support for Java™ by Red Hat v1.11.0

Obs: Copy from the bug found in another repository.
