Thanks. In 17, SystemLookup loads a specific library that is generated at build time - which contains all the c stdlib symbols. That's what the Lib.gmk changes are for. What I suspect is that the library is not generated at all, or not correctly on AIX, which then causes the system lookup to misbehave. I would start by double checking that you have a file like this: <JDK_ROOT>/lib/libsyslookup.so And then, if the library exists, check that it has the right dependency; on my linux it's an empty library, but which depends on libc, libm and libdl: ldd lib/libsyslookup.so linux-vdso.so.1 (0x00007fff2bdf7000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f35f1def000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f35f1ca0000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f35f1c9a000) ------------- PR: https://git.openjdk.java.net/jdk/pull/4316
