> Any chance we can get some performance improvement by replacing all uses of StringBuffer in org.drools.util.StringUtils with StringBuilder?
> If the minimum JVM version for drools is 1.5 StringBuilder is more efficient than StringBuffer for all the current uses in this code.
> From the javadocs:
> 'This class is designed for use as a drop-in replacement for StringBuffer in places where the string buffer was being used by a single thread (as is generally the case)'
