Yes, good idea:
[3e89d40253b70251f9a2facce4b1d8d69701c045](https://github.com/openjdk/jdk/pull/11513/commits/3e89d40253b70251f9a2facce4b1d8d69701c045)
I also fixed a bug due in the size computation of `path`. Ideally, I'd factor
out and re-use the same code in `ClassLoader::add_to_exploded_build_list`.
However, the latter uses a `ResourceMark` which is not available when calling
`is_module_resolvable` early in VM startup before `JavaThread` is initialized.
