问题
I have a problem while instantiating the Chaincode in Hyperledger Fabric v1.3.
In the tutorial 'Building your first network' on the official website of Hyperledger Fabric, the java chaincode was successfully instantiated without any problems.
However, When I created a chaincode that I made myself, the following lscc error is occurring:

Reproduced the same problem v1.3 Java SDK + Java Chaincode instantiation :) several times, GO chain code works just fine. Probably a bug with Java chain code compatibility instantiation.

Whereas go chain code works perfectly fine, no other difference in code Install works fine, instantiate Java chaincode always times out 2018-11-08 20:48:27.686 UTC [lscc] executeInstall -> INFO 031 Installed Chaincode [SimpleChaincode] Version [1] to peer
Reproducible again and again only with java chaincode instantiation with same logs, go chaincode instantiate works fine: https://hastebin.com/osafazisaj.rb
when I switch from Kafka to SOLO orderer, I get a better and different exception, as occassionally Kafka orderer would freeze causing docker network saturation? Switching to SOLO throws the error: failed to invoke chaincode name:"lscc" , error: timeout expired while executing transaction
