google safebrowsing api java client is giving: java.io.IOException: insufficient data written

[Priyanka Tanvani]

When i'm using the google safebrowsing api through the google java client for the same(https://developers.google.com/resources/api-libraries/documentation/safebrowsing/v4/java/latest/) it is working fine when I'm trying to make one api request at a time.

Now, i'm trying to make simultaneous requests for full hashes using the java ExecutorService threadpool, i'm getting the following error :

java.io.IOException: insufficient data written

I'm adding around 5000 prefixes in each findFullHashes request in both cases(single request at a time and multithreading). Can anyone please point out my mistake?
