  ...Camel will use your custom GroovyShell instance (containing your
  custom static imports), instead of the default one.

  If you need to use the xref:ROOT:properties-component.adoc[Properties] component from a
  script to lookup property placeholders, then its a bit cumbersome to do
  so.
  For example to set a header name myHeader with a value from a property
  placeholder, which key is provided in a header named "foo".
