OpenJDK binding for MMTk
MMTk GCs could not run hbase due to the incorrect or missing implementation of heap stat hooks. Probably related to these two methods: https://github.com/mmtk/mmtk-openjdk/blob/master/openjdk/mmtkHeap.hpp#L93-L94 ## Steps to run hbase and...
Based on the results from https://github.com/mmtk/mmtk-openjdk/pull/211, created from `ci-expected-results.yml` introduced in the PR. We may still have random failures that we haven't noticed. We should create separate issues if we...

*(Moved from https://github.com/mmtk/mmtk-core/issues/353)* Some structs in the mmtk-openjdk binding have fields that defers between debug/release builds of the C++ code of OpenJDK. Currently, we use the directive `#[cfg(debug_assertions)]` to make...

Related with https://github.com/mmtk/mmtk-core/issues/688. Unless mmtk-core fixes the issue, we expect to see mark sweep plan fail randomly or deterministically on tight heap (e.g. 2.5x MC min heap). ```console ----- mkdir...
