Some features get packaged as JAR during <buildProduct>

Hello,

my product build is feature based. If i export the features via "buildFeature" i can define "packageAsJar="false". But if i do a full product export, these features will be jar'ed and i seem not to have a possiblity to change these behavior.

The problem is, that the created product will not startup and crash with an error, if the features are jar'ed. Is there any possiblity to define the feature jar behavior during "buildProduct" ?
