jvm top command not working

[fabian-om]

The jvm top command is not working, even on the live demo: http://try.crashub.org/

% jvm top
jvm top: exception: No signature of method: crash.commands.base.jvm.eval() is applicable for argument types: (java.lang.String) values: [jvm heap]
Possible solutions: every(), getAt(java.lang.String), equals(java.lang.Object), heap(org.crsh.command.InvocationContext), pool(java.util.List), each(groovy.lang.Closure)
