Why is access restricted to jre6/lib/rt.jar for OperatingSystemMxBean?

Question

I'm having a little trouble with some Java code I'm trying to compile in Eclipse. I keep getting the following warning...

Access restriction: The type OperatingSystemMXBean is not accessible due to restriction on required library C:\Program Files\Java\jre6\lib\rt.jar

From this line of code...

com.sun.management.OperatingSystemMXBean bean = (com.sun.management.OperatingSystemMXBean) java.lang.management.ManagementFactory.getOperatingSystemMXBean();

I've found ways around this but I'm worried about the restriction warning. This code is for my open source project (CfTracker) and I don't want to work around this restriction if I'm going to be breaking some sort of license agreement. Can anyone help me understand this?

Answer 1

Go to Window-->Preferences-->Java-->Compiler-->Error/Warnings. Select Deprecated and Restricted API. Change it to warning. Change forbidden and Discouraged Reference and change it to warning. (or as your need.)

Thanks.
