exe="/usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt/bin javac" sig=11 That's what we're looking for. Looks like MLS issues, but I'd let someone from the desktop world weigh in. Since you have syscall auditing enabled you don't need strace. But as far as running javac in strace, something like: strace javac foo.java would be an example command. Actually I take back that MLS issue, I have no idea, wait for those qualified for real answers.
