Hi, There seems to be a mismatch between the requirements of sshd-osgi 2.11.0 (via the ‘ssh’ feature) and the version of bouncycastle in Karaf 4.4.5, which is 1.75:
sshd-osgi 2.11.0 imports: org.bouncycastle.asn1.pkcs {version=[1.76,2), resolution:=optional} org.bouncycastle.crypto.prng {version=[1.76,2), resolution:=optional} org.bouncycastle.jce.provider {version=[1.76,2), resolution:=optional} org.bouncycastle.openssl {version=[1.76,2), resolution:=optional} org.bouncycastle.openssl.jcajce {version=[1.76,2), resolution:=optional} org.bouncycastle.operator {version=[1.76,2), resolution:=optional} org.bouncycastle.pkcs {version=[1.76,2), resolution:=optional} org.bouncycastle.pkcs.jcajce {version=[1.76,2), resolution:=optional} Bouncycastle jars included in karaf 4.4.5: apache-karaf-4.4.5/system/org/bouncycastle/bcprov-jdk18on/1.75/bcprov-jdk18on-1.75.jar apache-karaf-4.4.5/system/org/bouncycastle/bcutil-jdk18on/1.75/bcutil-jdk18on-1.75.jar apache-karaf-4.4.5/system/org/bouncycastle/bcpkix-jdk18on/1.75/bcpkix-jdk18on-1.75.jar The result is that an RSA host key cannot be generated due to: NoClassDefFoundError for org/bouncycastle/openssl/jcajce/JcaPEMWriter, even when bcpkix-jdk18on 1.75 is installed by the feature. We have worked around it by overriding the feature, but it would be great for this to be addressed in a 4.4.6 release. Thanks, Anthony
