            Bug ID: 1679
           Summary: [IcedTea7] Allow OpenJDK to build on PaX-enabled
                    kernels
           Product: IcedTea
           Version: 7-hg
          Hardware: all
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: IcedTea
          Assignee: gnu.andrew at redhat.com
          Reporter: gnu.andrew at redhat.com

If the kernel has PaX enabled with MPROTECT provisions, the OpenJDK build fails
in two places:

* Running the gamma test in HotSpot
* Running the just-built rmic in the make/com/sun/jmx/Makefile part of the JDK
build

Both are cases of running just-built code and require that the binary is first
PaX marked, disabling MPROTECT.

IcedTea currently does this via patching but it should be done in OpenJDK
itself to allow raw forest builds.
