Darrel Schneider commented on GEODE-2109:
-----------------------------------------
I found some additional calls to "submit" in HeapEvictor and will be changing
them to "execute" as part of the fix for GEODE-2811
> calling submit on ExecutionService can cause exceptions to be lost

> Key: GEODE-2109
> URL: https://issues.apache.org/jira/browse/GEODE-2109
> Project: Geode
> Issue Type: Bug

> Geode has a number of places that call submit on ExecutionService. The submit
> method returns a Future object. If the caller makes sure it calls "get" on
> the Future then all is well. But in many places geode is not calling get. In
> that case if the Runnable that was submitted throws an exception it gets
> stored in the get and never logged. This can make it very hard to diagnose
> problems.
> If the caller does not want to call get on the returned Future then it should
> instead call the "execute" method. In that case the exception will be
> unhandled and the unhandled exception handler code we have on the
> LoggingThreadGroup class will cause the exception to be logged.
> Here are the places that should be changed to use execute instead of submit:
> org.apache.geode.internal.util.concurrent.CustomEntryConcurrentHashMap.clear()
> org.apache.geode.internal.cache.DiskStoreImpl.executeDiskStoreTask(Runnable)
> org.apache.geode.internal.cache.lru.HeapEvictor.onEvent(MemoryEvent)
> org.apache.geode.distributed.internal.InternalLocator.restartWithDS(InternalDistributedSystem,
> GemFireCacheImpl)
> org.apache.geode.distributed.internal.FunctionExecutionPooledExecutor.FunctionExecutionPooledExecutor(BlockingQueue<Runnable>,
> int, PoolStatHelper, ThreadFactory, int, boolean)
> org.apache.geode.internal.cache.PRHARedundancyProvider.scheduleCreateMissingBuckets()
> org.apache.geode.distributed.internal.InternalLocator.startSharedConfigurationService(GemFireCacheImpl)
> org.apache.geode.cache.client.internal.SingleHopClientExecutor.submitTask(Runnable)
> org.apache.geode.management.internal.FederatingManager.submitTask(Callable<DistributedMember>)
