the following worked until 1.7 and does not in 1.8, 1.9 and 1.10

class CommonData {
String content = 'value'

class SpecificData extends CommonData {
public SpecificData() {
setContent('specificValue') // works fine in all versions
content = 'specificValue' // throws NullPointerException since 1.8

class MyPlugin implements Plugin {
void apply(Project project) {
project.extensions.create('data', SpecificData)

apply(plugin: MyPlugin)
println data.content
