RE: [javagroups-users] ENCRYPT1_4 Problem

[Ian L. <ian...@hu...>]

I have managed to get things somewhat up & running (the problem was that my
RSA provider could not be located). However, I'm seeing another problem:

I'm working with a small test app written specifically for playing with this
stuff; the test app is a small gui that bounces a packet of data from one
instance of the test programme running on one machine to another instance of
the same programme running on a different physical machine, updating an
integer with each bounce. I am able to start up the first instance without
any trouble but when I start the second instance of the programme, I see the
following exceptions repeated over and over in the debug window for the
second instance (the first instance continues to run quite happily):

java.security.spec.InvalidKeySpecException: Inappropriate key specification
	at
com.sun.crypto.provider.DESKeyFactory.engineGenerateSecret(DashoA6275)
	at javax.crypto.SecretKeyFactory.generateSecret(DashoA6275)
	at org.jgroups.protocols.ENCRYPT1_4.decodedKey(ENCRYPT1_4.java:534)
	at org.jgroups.protocols.ENCRYPT1_4.up(ENCRYPT1_4.java:340)
	at org.jgroups.stack.UpHandler.run(Protocol.java:55)

This is not a machine specific problem as the problem always occurs on the
second instance of the programme. The two machines do not appear to be
finding each other. I added the PRINT protocol to the stack and I see that
the first machine is reporting a "java.io.StreamCorruptedHeader: invalid
stream header" at the same time as the second machine is reporting the
InvalidKeySpecExtension shown above. I should also add that I am using the
latest Bouncy Castle provider: bcprov-jdk14-124.jar

Why don't you debug the JChannel constructor - I cannot tell from here 
what's wrong.

You could also enable full logging to see what's going on
