-----------------------------------------
Summary: GridUnsafe.allocateMemory throws OutOfMemoryError which
isn't handled
Key: IGNITE-8845
URL: https://issues.apache.org/jira/browse/IGNITE-8845
Project: Ignite
Issue Type: Bug
Components: general
Affects Versions: 2.5
Reporter: Mikhail Cherkasov
Fix For: 2.6
Attachments: Main.java
If there's no more native memory then Unsafe.allocateMemor throws
java.lang.OutOfMemoryError. Errors - is type of exception after which you can't
restore application and you need to close it and restart. I think in this case
we can handle it and throw IgniteOOM instead.
Reproducer is attached, it throws the following exception:
Exception in thread "main" java.lang.OutOfMemoryError
at sun.misc.Unsafe.allocateMemory(Native Method)
