[BUG] Can't seem to instantiate BtClientBuilder

[Larsg310]

Describe the bug I can't seem to create an instance of BtClient (both using shared and private runtime)

I have these snippets of code:

Running this code line by line will result in the first breakpoint being hit (Bt.client(BtRuntime)), but second breakpoint never gets hit...

In the logs I get this after the call to Bt.client(BtRuntime):

[23:08:34] [INFO] [BtRuntimeBuilder] Loading standard extension module bt.peer.lan.LocalServiceDiscoveryModule [23:08:34] [INFO] [BtRuntimeBuilder] Loading standard extension module bt.peerexchange.PeerExchangeModule [23:08:34] [INFO] [BtRuntimeBuilder] Overriding auto-loaded module bt.dht.DHTModule [23:08:34] [INFO] [BtRuntimeBuilder] Auto-loading module bt.portmapping.upnp.UpnpPortMapperModule with default configuration [23:08:34] [INFO] [BtRuntimeBuilder] Auto-loading module bt.tracker.http.HttpTrackerModule with default configuration

Nothing else relating to Bt appears in the logs... (I'm using Log4j to Slf4j)

Seems like it's stuck on creating the injector. Can you post a thread dump of the stuck process (it can be called from the debug pane in IDE or by using jmap)?

This is the thread dump from IntelliJ right after the Bt.client(BtRuntime) call. I'm calling this from the "Download Thread@6811" thread.

Though what seems weird to me, is that the thread doesn't wait, because any subsequent calls to the same thread still run directly.

This particular bug is solved! The reason: Java 9 modules!

After some debugging, I found out Guice isn't able to instantiate classes because the module system prevented that. I had to add an --add-opens to allow Guice to do it's job.

I am now able to instantiate and start an instance of BtClient, and I've successfully downloaded a torrent.

However, I'm getting some errors connecting to peers, do you mind if I post the logs here or should I make a new report?

They are both trimmed in size, as they are repeating the same thing over and over: bt.log bt-dht.log

Glad that you found the solution! As for peer connectivity issues, these are OK in general case, and there is a long-standing task to somehow address the log verbosity.
