ASF GitHub Bot commented on KAFKA-4290: --------------------------------------- GitHub user thisthat opened a pull request: https://github.com/apache/activemq/pull/284 Avoid overflow errors with timestamps Some comparisons with timestamp values are not safe. This comparisons can trigger errors that were found in other Apache projects, e.g. KAFKA-4290. I changed those comparisons according to what the Java documentation recommends to help preventing such errors.

This shortcuts the poll loop and results in a very tight event loop > which can saturate a CPU. We hit this case out of the box because Connect > uses a default timeout of {{Long.MAX_VALUE}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
