----------------------------------------

             Summary: Best effort check to detect a 32-bit JVM trying to allocate too big
amount of memory
                 Key: IGNITE-5248
                 URL: https://issues.apache.org/jira/browse/IGNITE-5248
             Project: Ignite
          Issue Type: Improvement
          Components: cache
    Affects Versions: 2.0
            Reporter: Alexey Goncharuk
             Fix For: 2.1


A follow-up on the user list discussion:
http://apache-ignite-users.70518.x6.nabble.com/Ignite2-0-memory-policy-limit-td12840.html

We can catch the IllegalArgumentException and see if the allocated space exceeds 2Gb. In this
case, we should suggest that user check that he is running a 64-bit JVM.
