[jboss-jira] [JBoss JIRA] Updated: (JBRULES-2912) Drools Planner Divide By Zero Error

[ https://issues.jboss.org/browse/JBRULES-2912?page=com.atlassian.jira.plug... ] David Faulkner updated JBRULES-2912: ------------------------------------ Description: In org.drools.planner.core.localsearch.DefaultLocalSearchSolver::solvingEnded, there is potentially a divide by zero that occurs on the line: long averageCalculateCountPerSecond = localSearchSolverScope.getCalculateCount() * 1000L / timeMillisSpend; if timeMillisSpend is zero. Although in theory the likelihood of this occurring in practically nothing, we have actually seen it occur on a POC project with long running Planner jobs. An appropriate guard should be added to this calculation to ensure that this error cannot occur. was: In org.drools.palnner.core.localsearch.DefaultLocalSearchSolver::solvingEnded, there is potentially a divide by zero that occurs on the line: long averageCalculateCountPerSecond = localSearchSolverScope.getCalculateCount() * 1000L / timeMillisSpend; if timeMillisSpend is zero.
