We have an IconLink component that uses renderComponent to write out an icon and its corresponding text link by taking in a listener parameter, imgSrc, and altTitle parameter.

When it tries to run our private String getLinkURL() method it prints the below stacktrace in the console. The icon and the text link still render and the link still works.

CODE SNIPPET that causes error:
return getDirectService().getLink(false, new DirectServiceParameter(this, DirectLink.constructServiceParameters(getParameters()))).getURL() + frag;

The service is injected.
@InjectObject("engine-service:direct")
public abstract IEngineService getDirectService();

STACKTRACE in console:

java.lang.VerifyError: (class: ognl/ASTAdd13700671Accessor, method: get signature: (Lognl/OgnlContext;Ljava/lang/Object;)Ljava/lang/Object;) Wrong return type in function
