Jnode 0.2.5-3629 BUILD FAILED at java/security/cert/X509CertSelector.java on Fedora 8 with IcedTea

I just grabbed a new source tree from SVN, and tried a build of Jnode 0.2.5 r3629 using Fedora 8 and the IcedTea.
The Fedora 8 release notes state that IcedTea is mostly there, "except for some crypto stuff" which I may have just found.
Oh well, it was worth a shot. I reported this here just to capture it, and listed as minor because this probably isn't how Jnode was intended to be built.
If I figure out a patch or workaround, I will post them as well.
