FULL PRODUCT VERSION :
java version "9-ea"
Java(TM) SE Runtime Environment (build 9-ea+110-2016-03-17-022235.javare.4664.nc)
Java HotSpot(TM) 64-Bit Server VM (build 9-ea+110-2016-03-17-022235.javare.4664.nc, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]


A DESCRIPTION OF THE PROBLEM :
When compiling project that contains annotations from the javax.annotation package, compiler error is reported that corresponding classes can not be found.

Problem occurs both when compiling entire project with Maven, or when trying to compile separate class with plain javac,

Attempts to compile with -addmods key (as suggested at https://bugs.openjdk.java.net/browse/JDK-8152842) failed as well.
Unfortunately there is little information on jdk9 javac options available, so probably I misused 'addmods' option.

REGRESSION. Last worked in version 8u72

ADDITIONAL REGRESSION INFORMATION:
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a class annotated with the annotation from javax.annotation package.
For example add a class-level annotation @Provider(1)

2. Compile the class with command:
javac -cp javax.annotation-api-1.2.jar Sample.java

where javax.annotation-api-1.2.jar is "Common Annotations for the JavaTM Platform API". Available at http://central.maven.org/maven2/javax/annotation/javax.annotation-api/1.2/javax.annotation-api-1.2.jar

3. JDK9 javac reports an error, compilation fails.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Class / project compiles successfully.
ACTUAL -
Compiler reports error, class / project won't compile.
