> The purpose of using static libraries is to build GraalVM Native image statically linked with Java native libraries, to shipping single executable without runtime dependencies from JRE.
> For some static libraries, it leads to an issue: if one static library is trying to load another static library in runtime using `dlopen` (and then uses `dlsym` to find symbols). With static libraries, this is not possible and all dynamic calls should be replaced.
> This happens in `libawt` while it loads `awt-xawt` or `awt_headless` and in `mlib_image`.
> Current PR fixes this issue for AWT libraries that allow building Swing/AWT applications as a Native image and have no runtime dependencies from JRE.
