problem building IDP 2.4.1

[Steven Carmody]

Hi,

I've been experimenting with some extensions to the current version of 
the IDP. Its been building fine for the last couple of weeks.

Today, out of the blue, this msg popped out of the ant deploy step:

BUILD FAILED
/home/stc/Downloads/shibboleth-identityprovider-2.4.1-SNAPSHOT/src/installer/resources/build.xml:20: 
java.lang.SecurityException: class 
"org.bouncycastle.asn1.DEREncodable"'s signer information does not match 
signer information of other classes in the same package

Looking back to the maven/compile and build step, I see that it 
downloaded three new bouncycastle jar files (two from 
repo.maven.apache.org, one from build.shibboleth.net).

Might anyone have any suggestions about what happened here ?

Thanks !
