Comments
This is likely the incomplete core file issue we see on macosx-aarch64, and is described in JDK-8318754. Closing as a dup of JDK-8318754.

SA is trying to get the value of the C string pointed to by the C++ symbol __ZN9CDSConfig20_static_archive_pathE. SA has what it thinks is the address stored in that symbol, and does a ps_read() of that address to get the page, For some reason the page read failing. Most likely SA has read the symbol table in incorrectly, so it has a wrong, or bad, address for the symbol. This might be related JDK-8294316, which dealt with symbol file issues, but was fixed. Possibly the fix has some holes in it. However, JDK-8294316 was only seen on x64 and this issue was on aarch64.
