Question

I have this following aspectJ class method which gives me the error,The type java.lang.charSequence cannot be resolved to a type error.

    call(void ServiceImplementation.displayBookDetails(String)) && args(name){
    String sqlText = "SELECT * FROM Books WHERE Name='"+name+"'";
    logger1.info("Before Aspect :: Display Book Details of " + name);

I am using Eclipse Kepler and my this project is built using jdk 1.7. I tried installing jdk 1.8 patch for Kepler but that doesn't help. It doesn't get installed and stops during the installation process. Please help.

Answer 1

It can be a sneaky Java8 interface problem. In Java8 the charSequence has a default method attached.

If you are using it from Java7 compiler doesn't allow you to use default methods.

Try to fix the jdk 1.8 patch setup.
