The intention behind that is: > - Many {{Error}} subclasses are recoverable for the TaskManagers, such as > failure to load/link user code > - We want to give eager notifications to the JobManager in case something > in a task goes wrong. > However, there are some exceptions which should probably simply terminate the > JVM, if caught in the task thread, because they may leave the JVM in a > dysfunctional limbo state: > - {{OutOfMemoryError}} > - {{InternalError}} > - {{UnknownError}} > - {{ZipError}} > These are basically the subclasses of {{VirtualMachineError}}, except for > {{StackOverflowError}}, which is recoverable and usually recovered already by > the time the exception has been thrown and the stack unwound. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
