----------------------------------------
Summary: Non-thread safe use of Random
Key: HTRACE-170
URL: https://issues.apache.org/jira/browse/HTRACE-170
Project: HTrace
Issue Type: Bug
Affects Versions: 3.3.0
Reporter: Vladimir Sitnikov
org.apache.htrace.Tracer#nonZeroRandom64 is obviously shares the same Random
instance between multiple execution threads.
That does not work.
Either {{ThreadLocal<Random>}} (1.5+) or {{ThreadLocalRandom}} (1.7+) should be
used.
Other places with the same problem:
org.apache.htrace.impl.CountSampler#random
org.apache.htrace.impl.MilliSpan#nonZeroRandom64
org.apache.htrace.impl.ProbabilitySampler#next
