The code is missing on jdk15u for linux ppc as well, so the code probably never ported to linux ppc. I will ping Thomas Stuefe from SAP to see if it is intentional. Thomas' reply: Just an oversight. I actually unified all that coding into os_posix.cpp for JDK 17, so now the protector is present everywhere. But seems it's missing in 16 and earlier for ppc. The problem is that ppc (all our ports, really) originally forked from either Linux or Solaris. And upstream devs only fixed things on Oracles main platforms so we had to regularly scan those for updates. Like a sideway upstream. Error-prone. It got better after we integrated our platforms into the OpenJDK and upstream became used to the idea of ppc and s390. Cheers, Thomas Filed upstream bug: https://bugs.openjdk.java.net/browse/JDK-8279077 Upstream bug is going to be fixed in jdk15u, then downport to 11u and 8u. The upstream fix has been integrated to JDK15u and started to downport to JDK11u and JDK8u. The patch has been integrated in upstream jdk15u, 11u and 8u.
