> On systems where UTF-8 is not the default charset parallel iteration over non-string keys fails.
> Non-string keys are mapped to strings prefixed by \uFEFF when the entry is stored. The key is URL-encoded and the prefix is stored properly. The GET /cacheName (all keys) response however uses the system-default charset and if that's not UTF-8 the prefix cannot be mapped and ends up being "?".
> To reproduce set the charset to ISO-8859-1 and run RestStoreParallelIterationTest and you should see failures similar to this one:
