Hi,

It's probably too late to object this change since it's about to enter
testing but I suspect this change could trigger FTBFS in libasm-java
reverse dependencies.

I said this because I could verify this specific change prevent
jitescript package [1] to be successfully built with libasm-java
5.2-1. When I built it with 5.1-2 or with a new release on 5.2
reverting only this change, everything works on my side.

As workaround, I ended using libasm4-java as B-D for that package but
this is not ideal.

The error messages I got when I use libasm-java/5.2-1 are:

ERROR] /home/miguel/packages/jitescript/jitescript-0.4.1/src/main/java/me/qmx/jitescript/MethodDefinition.java:[58,37] incompatible types: java.util.ArrayList<me.qmx.jitescript.VisibleAnnotation> cannot be conv
erted to java.util.List<org.objectweb.asm.tree.AnnotationNode>
[ERROR] /home/miguel/packages/jitescript/jitescript-0.4.1/src/main/java/me/qmx/jitescript/FieldDefinition.java:[25,35] incompatible types: java.util.ArrayList<me.qmx.jitescript.VisibleAnnotation> cannot be conve
rted to java.util.List<org.objectweb.asm.tree.AnnotationNode>

You can inspect those files at upstream if interested at [2] and [3].
