模块化OpenJDK11 Java映像在Linux上找不到动态库（例如libjava.so）

Question

I have compiled a modular Java application using OpenJDK 11.0.2 on Windows 10. I have downloaded the linux OpenJDK 11.0.2 jmods and I have used them to create a run-time image using jlink. I have copied the image to a CentOS 6.10 VM, and if I try to launch java (the one in the bin folder in of the image generated by jlink), it fails saying "Error: could not find libjava.so". The libjava.so file is in the lib folder of the run-time image. If I move the java executable to /usr/bin and the libjava.so to /usr/lib, it complains about not finding a different .so file, so I guess this means that it expects to find the contents of the lib folder in the /usr/lib directory. On Windows there is no such problem (ie if I create an image using the Windows jmod files). I'm reluctant to solve this problem by creating an installation script that creates tenths of symlinks, but I can't think of any other solution. I have also tried to define a $JAVA_HOME variable that points to the [run-time image]/bin folder, but it still doesn't work.

Answer 1

I did some more tests and I have found the reason for this misbehaviour. The real problem was that I was using an output path (ie a value for the --output option) which ended with a directory called "bin" and this apparently causes Java to not find the dynamic libraries it needs, perhaps because it tries to locate them relative to the bin folder generated by jlink. So, for example "--output bin" or "--output dist/bin" don't work, while for example "--output dist" or "--output bin/dist" work.
