Circular dependencies when trying to backport antlr4

[Andreas Tille <andreas@an3as.eu>]

Hi,

I'm trying to backport antlr4 to Jessie.  It Build-Depends

   libantlr3-runtime-java
   libstringtemplate4-java (>= 4.0.8)

When trying to backport these I get the following Build-Depends:

   antlr3:
       libstringtemplate4-java (>= 4.0.8)

   stringtemplate4:
       antlr3 (>= 3.5.2)
       antlr3-maven-plugin (>= 3.5.2)

Bummer - which one is hen and which is egg?

Any hint how to break this circle?

Kind regards

      Andreas.
