IncludeProperties regex is incorrect

[GoogleCodeExporter]

this is my regex in xml:
<param name="includeProperties">
    \[\d+\]\.[^.]*$,
    \[\d+\]\.children\[\d+\]\.catName
</param>
but the property [0].children[1].catName
is ignored.

It shouldn't be ignored based on the regex expression 
:\[\d+\]\.children\[\d+\]\.catName

seems a mistake in JSONResult.java
    if (patternPiece.endsWith("\\]")) {

this.includeProperties.add(Pattern.compile(patternExpr.substring(0, 
patternExpr.lastIndexOf("\\["))));

                            if (log.isDebugEnabled())
                                log.debug("Adding include property expression:  " + 
patternExpr.substring(0, patternPiece.lastIndexOf("\\[")));
                        }

should be:

     if (patternPiece.endsWith("\\]")) {

this.includeProperties.add(Pattern.compile(patternExpr.substring(0, 
patternExpr.lastIndexOf("\\["))));

                            if (log.isDebugEnabled())
                                log.debug("Adding include property expression:  " + 
patternExpr.substring(0, patternExpr.lastIndexOf("\\[")));
                        }
