> {{GridCacheDatabaseSharedManager}} checks page tags, when acquiring page write locks. If the actual tag doesn't match the expected value, then {{PageSupport#writeLock}} method returns 0 pointer, which results in JVM crash.
> A proposed solution here is to make {{GridCacheDatabaseSharedManager}} ignore the page tag, i.e. use {{restore=true}} option in {{PageSupport#writeLock}} method.
