Locating this inspection

By ID

ReferencesToClassesFromDefaultPackagesInJSPFile

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | JSP

NOTE: Such references will not be resolved during compilation of the JSP because a compiled class for the JSP will be usually placed in non-default package (for example, "org.apache.jsp" in case of Tomcat, "com.ibm._jsp" in case of WebSphere), but importing from the default package is not allowed in Java.
