JavaDocOfflineLink created with wrong quotes

Hi,
we tried to use the JavaDoc Link Option earlier today. After some troubles to get it to work, we found out that the generated javadoc.options file was incorrect - it misses quotes between the option values (external link url and local package list)

instead of
-linkoffline 'http://java.sun.com/javase/6/docs/api/ /usr/lib/jvm/java-6-sun/docs/api'

it needs to be
-linkoffline 'http://java.sun.com/javase/6/docs/api/' '/usr/lib/jvm/java-6-sun/docs/api'

Our solution to this is a small patch to JavaDocOfflineLink.java that adds those to the toString method.

We've tested it here and now it works

An example gradle snippet:

apply plugin: 'java'

javadoc {
options.linksOffline 'http://java.sun.com/javase/6/docs/api/', '/usr/lib/jvm/java-6-sun/docs/api'
}

We would be happy to supply any more information etc to help on this issue
