betanet examples - blockUntilComplete() hangs indefinitely
Both messaging and tokens examples show the desired results, but after blockUntilCompete() is called, the programs run indefinitely. I end up shutting them down. That's either using Bootstrap.LOCALHOST_SINGLENODE or Bootstrap.LOCALHOST_HOST.
I dug into the method, and it is an observer of the transaction being finalized on the DLT. So that doesn't seem to happen.
Thanks for your feedback @jim-obrien-orig!
A bit of a confusion on my end: what happens after that hour of hanging (the title and the description seems to suggest different things)?
I just kill the process. I updated the subject/description. Thanks for your help.
Thanks for the quick update.
This doesn't seem like the right behaviour. We'll have a closer look at exactly what's going on here. Stay tuned...
@methk @jim-obrien-orig Thank you for your continued engagement on this topic. I have had a look at this from a couple of different angles but I seem to have a problem reproducing the issue (I'm on mac too). I start to think this might be an environment issue.
Could you please give example of a bare minimum example code that triggers this for you? What does your build.gradle file look like? And how do you initialise your app and the RadixApplicationAPI instance ("bare minimum code snippet")?
Ok - here's too examples - either compiled against
implementation 'com.radixdlt:radixdlt-java:dbfd5064e5'
or compiled against release/1.0.0-beta.2
Both get subscribed messages, but hang indefinitely on blockUntilComplete()
This is the messages example that hangs:
package com.jimob.radix.examples;
import com.radixdlt.client.application.RadixApplicationAPI;
import com.radixdlt.client.application.RadixApplicationAPI.Result;
import com.radixdlt.client.application.identity.RadixIdentities;
import com.radixdlt.client.application.identity.RadixIdentity;
import com.radixdlt.client.atommodel.accounts.RadixAddress;
import com.radixdlt.client.core.Bootstrap;
import org.radix.utils.RadixConstants;
public class MessagesExample {
public static void main(String[] args) {
// Create a new public key identity
final RadixIdentity radixIdentity = RadixIdentities.createNew();
// Initialize api layer
RadixApplicationAPI api = RadixApplicationAPI.create(Bootstrap.LOCALHOST_SINGLENODE, radixIdentity);
// Sync with network
api.pull();
System.out.println("My address: " + api.getAddress());
System.out.println("My public key: " + api.getPublicKey());
// Print out all past and future messages
api.observeMessages().subscribe(System.out::println);
// Send a message to an address
RadixAddress toAddress = RadixAddress.from("JEbhKQzBn4qJzWJFBbaPioA2GTeaQhuUjYWkanTE6N8VvvPpvM8");
Result result = api.sendMessage(toAddress, "Hello".getBytes(RadixConstants.STANDARD_CHARSET), true);
result.blockUntilComplete();
}
}
Output:

Hi,
Facing exactly the same issue described above but on Windows 10 Pro using Java/JavaC 11.0.9 and com.radixdlt:radixdlt-java:dbfd5064e5.
Additionally, I had to add a line of code to address an issue related to "No password supplied for PKCS#12". Not sure if the rest are facing the same. But adding "System.setProperty("javax.net.ssl.trustStoreType", "JKS");" seems to do the trick.
The getting started example (https://docs.radixdlt.com/radixdlt-java/guides/getting-started), however, runs smoothly.
