That looks good to me.

LogParser.java
Is this change to make the LogCompilation tool parse older version of the log file?

 475             long inlineId = 0;
 476             try {
 477                 Long.parseLong(search(atts, "inline_id"));
 478             } catch (InternalError ex) {
 479                 // 0 is an acceptable default value.
 480             }

If that is the case, a better comment would be nice.

Roland.
