Very thanks Jean.

Steps to reproduce "left-recursive but not recognize" (this is an example)
0) Open ANTLRW
1) Open new doc in ANTLRW
2) Copy the content of the file in your new doc.
3) Press Debug button
4) From the last rule use refactor "Inline rule"
5) Press Debug button (in some case at this point you lost ANTLRW 
left-recursive)
6) Add and delete a space in the rule (make the document dirty)
7) Press Debug button (ANTLR recognize the left recursion, ANTLRW no)

This is the result of console:
[10:36:57] Aborting because the following rules are mutually left-recursive:
    [booleanTest, booleanFactor, booleanValueExpression, booleanTerm]
[10:38:09] Aborting because the following rules are mutually left-recursive:
    [booleanValueExpression]
[10:38:19] Aborting because the following rules are mutually left-recursive:
    [booleanValueExpression]
