Though the same code was getting to compiled successfully with JDK 1.6 version, after upgrading to JDK 1.8 it won't compile, saying java cannot access ....class file ...as class file not found though it exists.

I am compiling this in IntelliJ Idea 13 IDE, tried with both Rebuild option as well as configured ANT build - result is same.

Any help is highly appreciated.

class file for com.abc.xyz.orchestrator.dispatch.IDispatchRequest not found

This issue is resolved now :). It's basically related to class path setup and only applicable for JDK 1.8.

For ex : If class 'A' has a reference to class B and class B is implementing an interface say 'C' then javac in JDK 1.8 requires both class B as well as Interface C on the class path where as prior to 1.8 only having class B on the class path was enough.

Please refer https://bugs.openjdk.java.net/browse/JDK-8055048 for more info.
