Turning more optimization levels to -Os could present a problem if you want to have LTO support for the JDK's native code outside of HotSpot as was discussed elsewhere

Thanks for the heads up. Most  JDK libs are C , only very few contain C++ (I think harfbuzz is an example that comes to mind).   As pointed out,  libjdwp is not among the libs with C++.

Do you have an example of a bug caused by the issue you mention (and is this already documented in the JBS somewhere) ?
