There's a bug in GridCacheWriteBehindStore in the flusher method.
https://github.com/apache/ignite/blob/master/modules/core/src/main/java/org/apache/ignite/internal/processors/cache/store/GridCacheWriteBehindStore.java#L674
<https://github.com/apache/ignite/blob/master/modules/core/src/main/java/org/apache/ignite/internal/processors/cache/store/GridCacheWriteBehindStore.java#L674>
The logic states there that if flush thread count is not a power
of 2, then
perform some math that is not guaranteed to return a positive
number. For
example, if you pass this string as a key it returns a negative
number:
accb2e8ea33e4a89b4189463cacc3c4e
and then throws an array out of bounds exception when looking up
the thread.
I'm surprised this bug has been there so long, I guess people are not
setting their thread counts to non-powers-of-2.
