Hi Timothy,
I poked around using PackageAdmin and there don't appear to be any bundles
exporting org.bouncycastle.openssl when this exception occurs. I'm kind of
wondering why anyone would care what the common superclass of Exception and
PEMReader was.
Is there any description of how this weaving proxying works and which classes
it applies to?
Looking at the stack trace a bit more I wonder if this problem is entirely
generated by the weaving. The karaf blueprint plan involved has this:
<bean id="keyPairProvider"
class="org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider">
<property name="path" value="${hostKey}"/>
</bean>
The user code in the stack trace is:
>> at
>> org.apache.sshd.server.keyprovider.AbstractGeneratorHostKeyProvider.static_init_adba91ec_bc37_40fd_b525_04d6fddc476d0(AbstractGeneratorHostKeyProvider.java:44)
>> at
>> org.apache.sshd.server.keyprovider.AbstractGeneratorHostKeyProvider.<clinit>(AbstractGeneratorHostKeyProvider.java)
>
AbstractGeneratorHostKeyProvider is the superclass of
SimpleGeneratorHostKeyProvider and neither mention PEMReader. The other
subclass of AbstractGeneratorHostKeyProvider is PEMGeneratorHostKeyProvider
which does use PEMReader. Looking at the class file for
AbstractGeneratorHostKeyProvider in emacs I don't see PEMReader. So I would
guess that the reference to PEMReader might have been added by the weaving.
I don't have the time to pursue this further, and it looks like it could
involve a lot of work to make reliable. I think I will have to try patching
application 0.3 so it works.
thanks
