[magicus]

It turned out we have bugs when cross-compiling riscv, so my attempts at showing that this works in the Oracle CI system has been unsuccessful so far. But now I have a local fix for JDK-8300550 , and it seems promising.

[magicus]

The solution worked fine, and will be fixed with JDK-8300550.
