> Method LocalTransaction.getCommitNodes() was introduced when fixing ISPN-2317 but this aspect was overlooked during review.
> The problem appears because the topology id is not incremented by an update caused by leavers. So the check getTopologyId() != currentTopologyId is not reliable.
> Flagging this as an issue for now but maybe the fix will actually need to increment topologyId on every update, w/o any special treatment of leavers. That would automatically solve this issue and would also simplify the code in AbstractTxLockingInterceptor that solves the same problem as here (see usages of TransactionTable.useStrictTopologyIdComparison().
> Or we can fix this here to using the same approach as AbstractTxLockingInterceptor + TransactionTable.useStrictTopologyIdComparison().
