Exceptions are swallowed

[tadas-subonis]

I've got an exception

io.objectbox.exception.DbException: Entity is expected to have a no-arg constructor: Item

but it didn't surface until I've debugged it and captured it at BoxStore.java:670

It seems that this happens because the exceptions are not handled before they are let go to the ThreadPoolExecutor where they are swallowed.
