How to force interpreter show complete stack trace?

Is there any way to force Scala interpreter (started through SBT) to print complete stack trace. By default, less than 10 lines are displayed: 

scala> new CacheMonitoringClient
javax.management.InstanceNotFoundException: com.bea:Name=DomainRuntimeService,Type=weblogic.management.beanservers.domainrun
time.DomainRuntimeServiceMBean
        at weblogic.rjvm.ResponseImpl.unmarshalReturn(ResponseImpl.java:195)
        at weblogic.rmi.internal.BasicRemoteRef.invoke(BasicRemoteRef.java:224)
        at javax.management.remote.rmi.RMIConnectionImpl_921_WLStub.getAttribute(Unknown Source)

        at weblogic.security.Security.runAs(Security.java:61)
        at weblogic.management.remote.common.RMIConnectionWrapper.getAttribute(ClientProviderBas...

As a workaround I'm using try { new CacheMonitoringClient } catch { case ex => ex.printStackTrace} (explicitly wrapping the calls that throw the exceptions I'm interested in), but that really ugly...

Use lastException if you want just one thing:
