RFR: 8369949: Increase Xmx of TestWaste.java so the EdgeQueue is larger, to fix crash [v2]

[Kerem Kat]

> SIGSEGV is caused by a stack overflow in the VM Thread that is traversing the object graph via `BFSClosure::process`. When the `EdgeQueue` is full, `BFSClosure` falls back to DFS.
> 
> We could increase `Xmx` of the test, or work on finding a better heap percentage for `edge_queue_memory_reservation`.
> 
> Here `Xmx` is set to `2g`. More details in the issue.
