Hi,
I was playing with the issue related to searchable nested views [1] and it
turned out that the implementation would be much easier with Java 8's
default methods in interfaces. Unfortunately after switching compiler in
Maven configuration to Java 8 the compilation fails with quite complex
looking generics related error:
<code>

jenkins-core ---

</code>
I wonder if it is a known issue or maybe even anyone gave a look at it
already?
Changes in the configuration triggering that error are available in my
branch [2] (just in case :) ).
