Bitcoinj can be crashed with OutOfMemory by sending a message with a large claimed var_str length or bytes array length. The actual message size does not matter, it's the claimed length that matters. This affects all bitcoinj-based apps that receive messages including Multibit, Android Bitcoin Wallet, Mycelium and Hive. The fix limits accepted length to max message size (32 MB).

To get started, ensure you have the latest JDK installed, and download Maven from: http://maven.apache.org/ Then run "mvn clean package" to compile the software. You can also run "mvn site:site" to generate a website with useful information like JavaDocs. The outputs are under the target/ directory. Alternatively, just import the project using your IDE. IntelliJ has Maven integration once you tell it where to find your unzipped Maven install directory. Now try running one of the example apps: cd examples mvn exec:java -Dexec.mainClass=com.google.bitcoin.examples.ForwardingService -Dexec.args="<insert a bitcoin address here>" It will download the block chain and eventually print a Bitcoin address. If you send coins to it, it will forward them on to the address you specified. Note that this example app does not use checkpointing, so the initial chain sync will be pretty slow. You can make an app that starts up and does the initial sync much faster by including a checkpoints file; see the documentation for more info on this. Now you are ready to follow the tutorial: https://bitcoinj.github.io/getting-started
