Αποτελέσματα:

• Needed to add a suitable for 'SHA384withECDSA' provider into 'java.security' config-file.
• Supposedly SHA384withECDSA provided by sun.security.pkcs11.SunPKCS11 with NSS as the native backend, as described in: http://blogs.sun.com/andreas/entry/the_java_pkcs_11_provider with the following config-file:

name = NSS
nssLibraryDirectory = /usr/lib ## or /usr/lib/nss on Gentoo
nssDbMode = noDb
attributes = compatibility

• In fedora needed to install nss-devel-3.12.3-4.fc11.i586 due to a missing NSS lib.
• Debug java-prop: java.security.debug={all|provider|sunpkcs11}
• But NSS does *NOT* by default compile ECC! according to: http://www.mozilla.org/projects/security/pki/nss/nss-3.11/nss-3.11-algorithms.html
• BUT Testcrypto,java TestCase attached on first bug also fails in sun's jdkcat ../progress.txt
