commit bdde5a1a970ddc9007b28de4aa29d60ffa588f08
Author: Yigit Boyar <yboyar@google.com>

    Re-factor how errors are dismissed when query is re-written
   
    This CL changes how we handle errors/warnings if query is
    re-written.
    There was a bug in expandProjection where we would report warnings
    for things that Room already fixes automatically (b/140759491).
    The solution to that problem (I7659002e5e0d1ef60fc1af2a625c0c36da0664d8)
    solved it by deferring validating of columns until after re-write
    decision is made. Unfortunately, this required changing PojoRowAdapter
    to have a dummy mapping until it is validating, make it hard to use
    as it does have a non-null mapping which is not useful.
   
    This CL partially reverts that change and instead rely on the log
    deferring logic we have in Context. This way, we don't need to break
    the stability of PojoRowAdapter while still having the ability to
    drop warnings that room fixes. This will also play nicer when we
    have different query re-writing options that can use more information
    about the query results.

I catch the exception again. As you can see below. but I have see that that error only happen when I run clearAllTables in Main Thread.

I know that we should not do that, and when I run clearAllTables in a background thread it runs without errors.

So I believe that the exception gives a wrong message.

clearAllTables is not supposed to be run in a main thread. It is annotated with @WorkerThread, and you should always run it in a background thread.
