Description

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.
