Description

While improving the org.apache.karaf.features.AppendTest I found that there is a case where the FeatureConfigInstaller behaves incorrectly.

If you add cfgFile.createNewFile() to testAppend then the code does not use the java Property class to write the config but the felix TypedProperties.
The resulting file looks like this:
javax.servlet.context.tempdir = ( \
\
"data/pax-web-jsp", \
\
)

This is incorrect as the property javax.servlet.context.tempdir contains a simple String not an array.
