Some users on the FreeBSD-java mailing list feel that the permissions checking in linux_sched_getscheduler are far too strict. Don Bowman <don@sandvine.com> has submitted the following patch. >How-To-Repeat: Install the port linux-sun-jdk14 on a system that does not have linux_base-6 installed (note, linux_base-6 is not susceptible to this problem). linux_base will be installed as a dependency. Now, try to run any of the Java binaries. All of them will throw a Java exception. >Fix: Here is the email from Don Bowman, including his patch. <http://docs.freebsd.org/cgi/getmsg.cgi?fetch=132728+0+archive/2002/freebsd-java/20020714.freebsd-java>; According to the following email, both sched_getscheduler and sched_getparam need to be patched, but the patch does indeed work. <http://docs.freebsd.org/cgi/getmsg.cgi?fetch=168075+0+archive/2002/freebsd-java/20020714.freebsd-java>; >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
