This is probably related with bug 498288. Although I had no difficulties on x86, dev-java/icedtea-7.2.4.5[pax_kernel] does not compile on amd64: paxctl -m fails with the message that some file needs to be converted. Patching PAX_COMMAND_ARGS to "-cm" led later to a message I forgot, but the effect was that a file was produced for which "ldd" gave an error, although the file could be executed. (My guess is that paxctl -c converted this file by mistake; might have been a 32 bit file?). Undoing the patch but passing instead EXTRA_ECONF=--with-pax=paxctl-ng (with installed sys-apps/elfix) helped, therefore the conjecture that this is related with bug 498288. However, for a successful compilation, I had to switch off PAX nevertheless, since otherwise compilation would die with the error that the java vm runs out of memory. I do not run an xattr pax mark only system, but hardened-sources-3.13.1 kernel (some rules concerning xattr have changed in recent versions, requiring to use paxctl-ng in any case.) It is remarkable that none of these problems occured on an x86 chroot.
Released in 2.3.14 & 2.4.6, ebuild in overlay: http://bit.ly/1rKqaoa
it should be fixed with the latest bump.
Confirming: it is fixed.
Marking as FIXED.
