Research direction

Start with AbstractEarModule.java:336-338 and the EarModule interface documentation for getArtifact(). Exercise the generateId path with an unresolved artifact and verify that it no longer throws a NullPointerException while resolved artifacts still receive their generated IDs.

Description

In AbstractEarModule.java:336-338, a NullPointerException occurs if generateId is true but the artifact has not been resolved:

if (generateId) {
    Artifact theArtifact = getArtifact();
    String generatedId = theArtifact.getType().toUpperCase() + "_" + theArtifact.getGroupId() + "."
            + theArtifact.getArtifactId();

getArtifact() is documented in the EarModule interface as returning null until the artifact is resolved. If a module's artifact is not yet resolved when generateId is true, .getType() throws an NPE.

Expected behavior

Add a null check before generating the ID:

if (generateId) {
    Artifact theArtifact = getArtifact();
    if (theArtifact == null) {
        return;
    }
    ...
}
