Log:
Merged revisions r1203047 r1203049 r1203052 from tomcat/trunk:
Reduce overhead from exception handling, using
ProxyDirContext.NOT_FOUND_EXCEPTION as an example.
Limit second string scan using results from the first one.
Use findByte() instead of indexOf(). Implementation is the same, but it is more
fair to its arguments.
