After trying to fix this on my own from what I have seen around the net I cannot still figure out what this means:

I fixed a similar problem by choosing an alternative set of the dependencies while migrating a project from Eclipse to Android Studio. Initially I used springframework.web and javax.xml.transform to make my code pass the build. But the app aborted immediately at runtime with "Ill-advised" error. Then I replaced those two dependencies with 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE', 'org.codehaus.jackson:jackson-mapper-asl:1.9.13' and 'org.codehaus.jackson:jackson-core-asl:1.9.13'. The problem solved.
