Checkstyle doesn't work with SuppressionCommentFilter - checkstyle

Question

Below is my code around check style - but it doesnt seem to suppress the audits between the suppression comment lines. I also tried with inline comment // instead of /* */
Please help. I have trying a lot of ways - permutation/combinations of those to get this fixed. Thank you.
Please let me know if you need more info.
/* CHECKSTYLE:OFF */
private abc createTimerChart(String title, String yAxisLabel, XYDataset dataset) {
final abc chart = ChartFactory.createXYLineChart(title, // chart title
"Time Elapsed (" + pollUnit.toString() + ")", // x axis label
yAxisLabel, // y axis label
dataset, // data
PlotOrientation.VERTICAL, true, // include legend
true, // tooltips
false // urls
);
/* CHECKSTYLE:ON */
CONFIG.XML reads:
<module name="FileContentsHolder">
<module name="SuppressionCommentFilter">
<property name="checkFormat" value="IndentationCheck"/>
</module>
</module>
AFTER MOVING SuppressionCommentFilter UNDER CHECKER:
<module name="Checker">
<!-- setting the default severity to warning -->
<property name="severity" value="warning" />
<module name="SuppressionCommentFilter">
<property name="checkFormat" value="Indentation"/>
</module>
<!-- No TAB characters in the source code -->
<module name="FileTabCharacter" />
<!-- List of files to ignore . -->
<!-- TODO Add all auto-generated files to this file -->
<module name="SuppressionFilter">
<property name="file" value="checkstyle/kepler-checkstyle-suppressions.xml"/>
</module>
<module name="TreeWalker">

The indentation check is called Indentation. It shold work if you change the checkFormat property to just Indentation:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE module PUBLIC "-//Puppy Crawl//DTD Check Configuration 1.3//EN"
"http://www.puppycrawl.com/dtds/configuration_1_3.dtd">
<module name="Checker">
<property name="severity" value="warning" />
<module name="TreeWalker">
<module name="JavadocType" />
<module name="Indentation" />
<module name="FileContentsHolder"/>
</module>
<module name="SuppressionCommentFilter">
<property name="checkFormat" value="Indentation" />
</module>
</module>
Or, more generally, I would recommend not setting the checkFormat property at all, which will make the suppression comment suppress all warnings for that block of code.
