Other situation producing the same problem. If next code is replaced by
lambda and method reference... the next block end up being optimized as if
response is always null.
//noinspection Convert2Lambda,Anonymous2MethodRef IGP-1732 gwt optimize
incompatible
tracker.add(heads.subscribe(new Action1<SubscriptionResponse>() {
@Override public void call(SubscriptionResponse response) {
ClientTelemetryStore.this.processResponse(response);
}
}));
The processResponse java code.
private void processResponse(SubscriptionResponse response) {
Objects.requireNonNull(response, "response required");
Objects.requireNonNull(response.getUuid(), "response.uuid required");
if (uuid == null) uuid = response.getUuid(); // first response
else assert uuid.equals(response.getUuid()) : "subscription uuid mismatch";
boolean newUnits = false;
for (UnitDescriptor xs : response.getUnits()) {
newUnits |= processUnitCreate(xs);
}
for (ProtoUnit xs : response.getData()) {
processUnitUpdate(xs);
}
// accumulate change updates per response
if (newUnits) tStoresChange.onNext(tStores);
}
And processResponse js code.
function Hak(a, b) {
var c, d, e, f;
lWl(b, 'response required');
lWl(null ._0(), 'response.uuid required');
a.g = null ._0();
c = false;
for (f = null ._0()._0(); f.Nd(); ) {
d = Vub(f.Od());
c = c | Iak(a, d)
}
for (e = null ._0()._0(); e.Nd(); ) {
d = Uub(e.Od(), 6163);
Jak(a, d)
}
c && lrm(a.d, a.c)
}
