I am concerned that something that [JDK-8303796](https://bugs.openjdk.org/browse/JDK-8303796) claimed to be a small enhancement is in fact requiring a lot of changes in different areas of the codebase. There are already a number of "duplicate symbol definition" issues that have been filed and fixed in an ad-hoc manner in the JDK, which is the kind of whack-a-mole approach that we should not be taking. If static linking requires symbol isolation then a generally applicable approach to doing that should be investigated (in a separate project? Leyden?) and then brought to mainline via a JEP (not just for the hotspot aspect as currently suggested).
