Cannot istall java: pax-marking doesn't work properly with paxctl-ng

I've discovered, that I cannot install the latest java update. I use sun-jdk.
Emerge dies with an error message showing that binaries of the package
about to be installed aren't pax-marked properly.
It turns out, that java-vm-2.eclass will call pax-mark with -Cm flags on
amd64. While paxctl-ng will refuse to alter the binary with the -Cm
combination. I can -C first, and -m after that. But the two flags together
in a combination will cancel the operation.
Either the eclass should do it in two steps, or paxctl-ng binary must be
altered to handle this combination of flags (-Cm on amd64).
I'm using elfix-0.8.1 package.

Regards: Dw.

Before reading the bug I modified the eclass exactly the same way how it
has been mentioned. And it solves the problem apart from the ongoing
discussion in the bug's thread.

I'm too late as I see, but for the record I did this:
--- java-vm-2-original.eclass 2013-02-08 00:11:02.531340263 +0100
+++ java-vm-2-dwokfur.eclass 2013-02-08 00:12:34.260199247 +0100
@@ -279,8 +279,11 @@

# Ensure a PaX header is created.
local pax_markings="C"
+
+ pax-mark ${pax_markings} $(list-paxables "${executables[@]}")
+
# Usally disabeling MPROTECT is sufficent.
- local pax_markings+="m"
+ local pax_markings="m"
# On x86 for heap sizes over 700MB disable SEGMEXEC and PAGEEXEC
as well.
use x86 && pax_markings+="sp"

So duplicated the pax mark for a separate C and m. I doesn't take care of
the ze problem.
