Greetings! I am configuring DOMjudge 5.0.1 in a Fedora 22 64-bit environment. Most things seem to be working.
I am trying to get Oracle Java 8u60 to run correctly in a "chroot" environment. I built the chroot directory more-or-less manually, installing Java into it (under /opt) and copying the necessary library files. I also copied /bin/bash into the chroot area along with its necessary library, and linked sh to bash. I edited the java_javac_detect script to run /opt/java/bin/java as "program".
If I run a chroot command from the shell, bash starts, and I can run "/opt/java/bin/java -version". It complains about the lack of a monotonic clock but otherwise seems to run.
I then tried to run the "Hello World" tests. C and C++ work fine. Java fails. I went into the execution directory and the program.err file says that it could not exec /opt/java/bin/java.
Has anyone tried to get this kind of configuration running? Any ideas about how to best configure Java in this environment? Suggestions will be greatly appreciated.
Marc
