(In reply to Eclipse Genie from comment #1) > New Gerrit change created: https://git.eclipse.org/r/47916 Victor, Do you have steps to verify that adding this condition works ? I will also suggest to add isReadOnly call before delete of partition.
Sarika, (In reply to Sarika Sinha from comment #2) > Victor, Do you have steps to verify that adding this condition works ? The failure came from Error Reporting System, so I have no steps to reproduce (and I had no luck in trying to reproduce it by myself). It looks like failure came from some 3rd-party console adaptation but I can't see any 3rd-party classes in the stacktrace provided to be sure in this opinion. > I will also suggest to add isReadOnly call before delete of partition. I wouldn't use isReadonly() and here is the reason: The check for (IOConsolePartition.INPUT_PARTITION_TYPE.equals(partition.getType())) does practically the same (since both, the type and the read-only flag, are private and are set in constructor. When an output-type partition is created - there is no a buffer created for such partition and there is no way to create such a buffer 'from outside'. So the check like 'type == IOConsolePartition.INPUT_PARTITION_TYPE' guaranties that delete() call is enabled on a partition. The read-only flag value may be used for the same purpose, but it's possible to change it by calling setReadOnly(false) on a partition 'from outside'. So, this won't give you a guarantee that the buffer is created. As such we couldn't be sure that we can use delete() call on such a partition. That's why I've not used isReadOnly() in the check before delete() call.
I think we can push this in 4.7 M1.
@Victor, the gerrit patch has id vrubezhny <vrubezhny@exadel.com> which is not registered, can you please do the needful ?
Moving to M6, as can't release the changes without id resolution in gerrit.
