FULL PRODUCT VERSION :
java version "1.8.0_141"
Java(TM) SE Runtime Environment (build 1.8.0_141-b15)

A DESCRIPTION OF THE PROBLEM :
There appears to be a bug in javac that's somehow related to an import of an inner-class of an inner-class. If the inner-inner-class is moved out so that it is an inner-class, compilation succeeds.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile the source code for the two classes that is provided below:

$ javac com/example/JavacProblem.java com/example/annotation/Configuration.java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The code compiles successfully
ACTUAL -
JavacProblem.java fails to compile on line 15:

$ javac com/example/JavacProblem.java com/example/annotation/Configuration.java
com/example/JavacProblem.java:15: error: cannot find symbol
@Configuration
^
  symbol: class Configuration
  location: class JavacProblem
1 error



REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
com/example/JavacProblem.java:

package com.example;

import com.example.JavacProblem.ConfigurationTwo.AnInnerClass;
import com.example.annotation.Configuration;

public class JavacProblem {

AnInnerClass customBean;

@Configuration
static class ConfigurationOne {

}

@Configuration
static class ConfigurationTwo {

static final class AnInnerClass {

}

}

}

package com.example.annotation;

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;

import java.lang.annotation.Target;

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Configuration {

}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Move AnInnerClass so that it is an inner class of JavacProblem rather than ConfigurationTwo
