While running the following code snippet at some scenario, I got the
java.util.ConcurrentModificationException exception.
Please advice: How to avoid it? what can be the worse scenario which
ConcurrentModificationException
can create? will it occupy the CPU Usage %? Any pointer would be great!!!
public Map someMethod()
{
Map actionDosMap =new HashMap();
List associatedActionsDos =new ArrayList();
List associatedActionsPerormanceDos =new ArrayList();
Iterator iterActions =associatedActions.iterator();
while (iterActions.hasNext())
{
Iterator reposIt = reposSet.iterator();
while (reposIt.hasNext()) {
RepoRow row = (RepoRow) reposIt.next();
Properties props = row.getProperties();
DoData performanceReportsDo = new DoData();
if
("PerformanceReports".equals(props.getStringValue(do_type))) {
performanceReportsDo.setDoType(doType);
performanceReportsDo.setDoId(doID);
associatedActionsPerformanceDos.add(performanceReportsDo);
}
else
{
DoData doc = new DoData();
do.setDoType(doType);
do.setDoId(doID);
associatedActionsDos.add(do);
}
}
}
actionDosMap.put("performanceReportsDo",associatedActionsPerformanceDos);
actionDosMap.put("actionsNonPerfoDo",associatedActionsDos);
return actionDosMap;
}
