             Summary: NullPointerException prevents display of Coverage Report
                 Key: NETBEANS-5763
                 URL: https://issues.apache.org/jira/browse/NETBEANS-5763
             Project: NetBeans
          Issue Type: Bug
    Affects Versions: 12.4
         Environment: Netbeans 12.4 installed via snap on Ubuntu 18.04.

JRE is OpenJDK 11.

The project is a Java Maven project.

Code coverage is provided by: org.jacoco:jacoco-maven-plugin:0.8.6
            Reporter: Nathan Callister


Whenever I attempt to display the code coverage report I get the status bar 
below the code but I cannot view the report.

I am able to reproduce this every time, I am unable to not produce this.

Netbeans reports an unexpected error:
