FIXME on line 162 of util.py.

 src/vpp-api/java/jvpp/gen/jvppgen/util.py

 The issue is any API definition with the suffix _counters or _event is treated special by the API gen, resulting in a Java DTO of "Foo"+Notification.java instead of "Foo.java". Hence JVPPGEN complains about "Can't find Foo.java".

WORKAROUND: rename API definition to something else ie.

want_foo_counters -> want_foo_stats (which ends up streaming a vnet_foo_counters_t to client).
