InfluxDBException: 'error parsing query' - Error is not propagated to Consumer callback

Hello,

please take a look at InfluxDBImpl.java#L548

If you throw an InfluxDBException an this position, it is not possible to catch it on the caller side:

public void loadDataAsync(int chunk, Consumer<QueryResult> consumer) {
    // Bad syntax test
    db.query(new Query("SELECT * FROM sieries LIMIT -100", databaseName), chunk, consumer);
}

Stacktrace:

org.influxdb.InfluxDBException: {"error":"error parsing query: found -, expected integer at line 1, char 63"}

This causes my REST-Endpoint (Spring MVC) to hang.

Start in src/main/java/org/influxdb/impl/InfluxDBImpl.java around the referenced line and trace the asynchronous query response handling shown in the stack trace. Reproduce the invalid-query case, then verify that the Consumer callback receives the error and the calling REST endpoint no longer hangs.
