{noformat}
This is due to an old (pre-SLING-4114) assumptions on RequestProgressTracker
output.
SLING-4114 removed date and time fields which were ending in closing
parenthesis but the analyzer is still looking for it while calculating string
index. In most of the cases the request details are just wrongly displayed, but
when the closing parenthesis character is at the end of the string then the
index exceeds string length resulting in the exception. The solution is to
update the code to the current RequestProgressTracker output format without
those removed fields.
