Reporting of processing time does not work:

• maxProcessingTime is always 0 (zero)
• processingTime is huge negative number, for example -8487404155063010

Root cause is very simple and obvious from sources:

1. request start time is recorded in nanoseconds (System.nanoTime())
2. request end time is taken in milliseconds (System.currentTimeMillis())
3. their difference is, therefore, huge negative number
