> This patch adds a simple policy to put a limit on field flattening to prevent > instances from becoming too large. It is easy to generate very huge instances > with nested flat values, so huge that the JVM struggles to allocate its > internal data structure to handle such classes. The new policy allocates a > flattening budget to each class, and field flattening in this class stops > when the budget is exhausted. The limit can be tuned with a VM parameter. > > Tested on Mach5 tier1-4 > > --------- > - [X] I confirm that I make this contribution in accordance with the [OpenJDK > Interim AI Policy](https://openjdk.org/legal/ai).
