titan-cassandra 1.0.0 with guava 25.0-jre fails

[hemabs]

I'm trying to use titan-cassandra 1.0.0 with guava-25.0-jre. Upon upgrade of guava from 18.0 to 25.0-jre, I see below run time exception:
[artifact:mvn] java.lang.IllegalAccessError: tried to access method com.google.common.collect.Iterators.emptyIterator()Lcom/google/common/collect/UnmodifiableIterator; from class com.thinkaurelius.titan.graphdb.query.QueryProcessor

Can you let me know if these are compatible?Thanks.
