So "ABStatus" cannot be recognized as valid constant name. However, in my real-world project, we use GSStatus as the enum class name. I have to change it to GsStatus currently. I suggest changing this pattern to \{code:java} " \ [a-z\\ \\ d] + \\.( \ [A-Z]+ \ [a-z\\ \\ d]+)+\\ \\ $?( \ [A-Z] \ {1} \ [a-z\\ \\ d]+)*\\ \\. \ [A-Z_ \\ + + $]+". \{code} I have written a simple project for finding this issue. You can refer it as reference.
