@aledsage, thanks a lot for your explanation.
I see the problem about `ImmutableMap` now and I understand the difference
between both of them, so I will use `MutableMap`.
About the exception, the method terminated propagating a
`NullPointerException` and I saw a `NullPointerException` in the console, but I
did not understand why a `NullPointerException` was thrown. Then, I found an
`InterruptedException` in the stack. I do not know if it makes sense for you,
but this `InterruptedException` helped me to understand the problem and then I
decided to save a copy of the information that was being accessed.
