> {code}
> Local references are only valid in the thread in which they are created. The native code must not pass local references from one thread to another.
> {code}
> We have two places where we DO pass local JNI reference to another thread:
> * CacheParallelLoadStoreAdapter
> * CacheTestStore.LoadCache
> For some reason it has worked for us before.
> But renamings in IGNITE-1881 have caused test execution order to change, and these store tests cause process crash.
> To reproduce, BinaryBuilderSelfTest (former PortableApiSelfTest) has to be executed before store tests. All other tests can be excluded. 100% repro rate: "FATAL ERROR in native method: Bad global or local ref passed to JNI".
