We encountered following linker error when statically linking JDK/hotspot native libraries with user natives:

ld: error: duplicate symbol: normalize
>>> defined at FileSystemSupport_md.c:112 (/.../src/java.instrument/unix/native/libinstrument/FileSystemSupport_md.c:112)
>>> libinstrument_relocatable.o:(normalize) in archive .../lib_static/libinstrument.a
>>> defined at adjust.c
>>> .../adjust.o:(.text+0x0)

https://gitlab.com/graphviz/graphviz/-/blob/main/lib/neatogen/adjust.c#L830 is an example of the code defines 'normalize'.

This is the last set of duplicating symbol issue related to JDK-8303796 that we've noticed with our prototyping for static JDK support on JDK 11. All other issues found with JDK native and hotspot code (not including third party code such as zlib) have been reported with bugs linked in JDK-8303796.
