Description

My project consists of the default App.java class, from running "maven genapp", and the following Java 5 enum class, State.java:

package example.app;

import java.awt.Color;

public enum State
{
OK, WARN, CRITICAL;
}

The project compiles fine. When I run "maven site", I get the following error from JXR:

[echo] Generating the Source Xref...
maven-jxr-plugin:report:
[echo]

PackageManager -> parsing... example/app/State.java
Unable to process /home/sscaring/tmp/test/src/java/example/app/State.java => /home/sscaring/tmp/test/target/docs/xref/example/app/State.html

JXR does successfully create the x-ref for the App.java class. Thanks,

Hello,

It looks like this can be fixed by adding the following to line 110 of JavaFileImple.parse():

stok.sval.equals("enum"))
