Comments
The immediate cause is that C2 and Graal can eliminate allocations if it can be determined that they do not "escape". However, getContext relies on there being a concrete context object to retrieve. C2 workaround: -XX:-EliminateAllocations Graal workaround: -Dgraal.PartialEscapeAnalysis=false
