Steven Hawkins resolved TEIID-3422.
-----------------------------------
Fix Version/s: 8.11
Resolution: Done
Updated to use a long for the size variable and added a hard max of 1 GB for the max object size.

> Setting more than 513MB for buffer-service-max-storage-object-size, OOME occurs at org.teiid.common.buffer.impl.BufferFrontedFileStoreCache.initialize().
> One of our user needs to set more than 512MB for buffer-service-max-storage-object-size to avoid TEIID30001[1], this limitation becomes a critical issue for them.
> Additional Information:
> By taking look at the source code[2], if the value of maxStorageObjectSize is more than equals with 536870912, the loop becomes infinit, and will cause OOME.
> [1]
> TEIID30001 Max block number exceeded by 233,144 21,422,155. Increase the maxStorageObjectSize to support larger storage objects. Alternatively you could make the processor batch size smaller.
