Situation: I have a simple java application, which also reads a property file. It used to work fine in JDK 1.7.
Problem: After upgrading to JDK 1.8 and Tomcat 8, I get the following error:
The type java.util.Map$Entry cannot be resolved. It is indirectly referenced from required .class files
Things I did: I updated Eclipse plugins, I upgraded Tomcat 7 to Tomcat 8, and added ec-4.jar.
However, nothing worked, and the error still remains.
