Regression in JDK8 build 78: javac complains about missing Class#isAnnotationPresent

[Joe Darcy]

Hello Uwe,

One of the warnings you should have received from javac is JDK 8 is 
something along the lines of "using -source 6 without setting 
-bootclasspath."

If follow this long-standing recommendation,

     https://blogs.oracle.com/darcy/entry/how_to_cross_compile_for

then your existing code should compile.

Thanks for trying out the JDK 8 builds on Lucene,

-Joe

Unfortunately those bugs are fixed, but suddenly, the source code of Apache Lucene and Apache Solr no longer compiles, although valid in JDK6, JDK7 and earlier JDK8 builds. We get the following error:

The implementations were removed from the concrete classes, only the new default implementation on the interface should be used. Unfortunately, the compiler (javac) does not understand this and fails to compile. -target and -source is 1.6.
