-----------------------------------------------------------------
Looks like a missing type converter to me. The following work around seems to
fix the problem:
{code:java}
from("ftp://192.168.99.100/outbox?passiveMode=true&localWorkDirectory=/tmp&username=docker&password=docker&noop=true";)
.convertBodyTo(InputStream.class)
.convertBodyTo(StreamCache.class)
.wireTap("direct:mydirect");
from("direct:mydirect")...
{code}
