Certificate problem with hostet Nexus

Hey guys,

I have deployed the core.jar from processing.org to my own hostest nexus
repository
(https://nexus.cedarsoft.com/content/repositories/processing/org/processing/core/2.2.1/).

I have the following pom[1].
Running "mvn install" gives this output
[2]:"java.security.cert.CertificateExpiredException: NotAfter: Thu Oct
31 06:13:55 CET 2013"

I tried it on two different computers, same problem.
I am using Java 1.8.0_25 and Maven 3.2.3 using Linux.
I am using a startssl.com certificate. But I don't think this should be
a problem, since I have other repositories (maven central mirror) that
work fine.

Any ideas?

Thanks,

Johannes
