Problems running examples PrintPeers #1109

Open mik3hall opened 9 years ago

mik3hall commented 9 years ago

Same as first part of Trouble with Context on bitcoinj 0.13.2 #1093 https://github.com/bitcoinj/bitcoinj/issues/1093

Exception in thread "main" java.lang.IllegalStateException: You must construct a Context object before using bitcoinj! at org.bitcoinj.core.Context.get(Context.java:83) at org.bitcoinj.core.Peer.(Peer.java:227) at org.bitcoinj.core.Peer.(Peer.java:193) at org.bitcoinj.core.Peer.(Peer.java:174) at org.bitcoinj.examples.PrintPeers.main(PrintPeers.java:88)

Same fix worked... Context.getOrCreate(MainNetParams.get());

I was thinking of making this a separate issue because I thought I had another instance. But so far I guess this just came up on PrintPeers.

Exception in thread "main" java.lang.IllegalStateException at org.bitcoinj.net.NioClientManager.openConnection(NioClientManager.java:150) at org.bitcoinj.examples.PrintPeers.main(PrintPeers.java:121)

Adding these... clientManager.startAsync();
clientManager.awaitRunning();

after Line 83 NioClientManager clientManager = new NioClientManager();

seemed a workaround.

Thats strange, I just ran into this a well. I'll try your work around.

Update. No go. I ran into this issue in NetworkAbstractionTests. I tried adding awaitRunning, and the error turned into

java.lang.IllegalStateException: Expected the service NioClientManager [FAILED] to be RUNNING, but the service has FAILED
