v8Flags.setMaxHeapSize() is this for java heap memory or native memory?

[RakeshRaparthi]

I am using javet lib in java application, I just want o know v8Flags.setMaxHeapSize() is for heap memory or native memory? little bit confusing...
i believe this memory is sharedMemory for all engines. could anyone please clarify?
i have seen crash for big js payload like 30 mb having setMaxHeapSize as 4gb. what are recommend options.?

Please refer to the official doc , or leverage Node.js help for the answer.

node --v8-options | grep 'max-heap'
  --max-heap-size (max size of the heap (in Mbytes) both max_semi_space_size and max_old_space_size take precedence. All three flags cannot be specified at the same time.)
        type: size_t  default: --max-heap-size=0

If you still face issues, could you leave a repo with the issues?

I could n't find your doc which says using native memory or heap memory.
could you please share.

It is not managed by JVM.

is there any way to some control in java, we could catch it maybe we can retry?

There might be some ways of doing so, but those ways haven't been implemented anywhere. Not even in Chrome or Node.js. They just crash anyway. Please refer to this blog for detail.
