Unable to compile class for JSP: The type java.util.Map$Entry cannot be resolved. It is indirectly referenced from required .class files
- You have just upgrade to java 8.
- Yo haven't upgraded tomcat or you did.
Make sure you do not have an older ecj-*.jar file in your classpath. Removing the older jar will resolve the error. ecj-4.4.2.jar should work.
