More info about javac.. according to some blogs/forums, javac/java has to be of type textrel_shlib_t, and I can see that it has the right type.

Also run javac in strace and see where it's dying. Does this work in permissive mode?

I am wondering why, because both are in /usr/bin directory and both binaries have the same context.Can somebody please help?Thank you so much!Regards,Rahmadi
