Is there any plan to add support for retrieving input or output address when it's multisig? Right now it doesn't look like P2SH is supported

Hi guys,

first of all, THANKS for building this to facilitate Analytics on the blockchain!
I am trying to build this for a few weeks now following your instructions and am encountering an issue that I am unable to resolve:
Exception in thread "main" java.lang.ClassCastException: tcs.blockchain.bitcoin.BitcoinInput cannot be cast to scala.Tuple2

The detailed Runtime Warnings and Exceptions are below.

Could it be that based on the system specifications below my build results in missing generics for Java Collection classes like HashMap, ArrayList, Vector or Hashtable or type-safety being insufficient? I am a bit lost here and would appreciate some help.

• When building with jdk 9.0.1 instead of 1.8.0_152, I get the following error:
  error while loading package, Missing dependency 'object java.lang.Object in compiler mirror', required by /Users/me/.sbt/boot/scala-2.10.6/lib/scala-library.jar(scala/runtime/package.class)
  scala.reflect.internal.MissingRequirementError: object java.lang.Object in compiler mirror not found.

This can be resolved by building with Java 8 instead (which seems to be the common fix from what I read online) - For the sake of completeness, I attached the complete log file for this initial Java 9 error if that helps since it is the reason that forced me to build with Java 8 in the first place. I am unsure whether it is related to my current problem or not?

• I am also unsure about some of the WARNING messages below and whether they are part of the issue, but it really seems to be the casting that prevents the run from completing successfully.

Thanks so much.
Fred

Error Log when building with Java 9.txt

I'm testing import of the whole ETH chain into MongoDB. Blocks get imported except from height 2637146 onwards. Seems that the call web3j.ethGetBlockByNumber(new DefaultBlockParameterNumber(height), true).sendAsync().get().getBlock returns null for them. Successful reading resumes a little before height 4696000. Consequently, there are now almost 30 million documents (transactions) in my MongoDB but many may be missing.
