This LGTM. Perhaps wait for another approval from a reviewer?

libjsig is not supposed to be enabled by default. Per [Java 23 doc](https://docs.oracle.com/en/java/javase/23/troubleshoot/handle-signals-and-exceptions.html#GUID-CB49A2A7-2A9F-4C18-948F-6D4A96FF688D), it is user's choice whether to use libjsig.so. If they use it, they should either link the application with linker flag `-ljsig`, or use LD_PRELOAD.
