The problem is know upstream and related to use of Java 8:
https://github.com/antlr/antlr3/issues/151

So for a workaround, forcing compilation to use oracle-jdk-bin-1.7 makes it compile (e.g. JAVA_PKG_FORCE_VM=...).

Something like https://github.com/antlr/antlr3/commit/e88907c259c43d42fa5e9f5ad0e486a2c1e004bb could work for us, but to my current understanding it would need to be applied against antlr:0 since that is called to generate v3 grammars.  I could try to making a patch for antlr:0.

PS: We could also add a check for

  $(java-pkg_get-vm-version) == 1.8

if there is need for a different solution.
