Compress failed: String index out of range v1.5.1

I am using yuicompressor version 1.5.1.

Following is the pom.xml configuration for the plugin

<plugin>
    <groupId>net.alchim31.maven</groupId>
    <artifactId>yuicompressor-maven-plugin</artifactId>
    <version>1.5.1</version>    
    <executions>
        <execution>
            <id>compress</id>
            <phase>package</phase>
            <goals>
                <goal>compress</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <nosuffix>true</nosuffix>
        <linebreakpos>-1</linebreakpos>
        <aggregations>
            <aggregation>
                <removeIncluded>true</removeIncluded>
                <insertNewLine>true</insertNewLine>
                <output>${project.build.directory}/${project.build.finalName}/static/js/jquery/jquery.all.min.js</output>
                <includes>
                    <include>jquery-1.6.2.min.js</include>
                </includes>
            </aggregation>
        </aggregations>
        <excludes>
            <exclude>**/*.min.js</exclude>
            <exclude>**/push-crew/*.js</exclude>
        </excludes>
    </configuration>
</plugin>

I am getting the following error on tracing (-X) on my build process. I tried removing a couple of CSS files which are in the aggregations, but no help. The build process was working fine up until now.

Is this a problem with the plugin? what can be the possible solution? I can't use any other plugin as those are not in our repository. Please help me understand what is wrong here -
