It's very obvious that java-tron is based on the ethereumj project.
E.g. compare these two files (Just a random example out of many):
https://github.com/tronprotocol/java-tron/blob/develop/src/main/java/org/tron/datasource/leveldb/LevelDbDataSource.java
https://github.com/ethereum/ethereumj/blob/develop/ethereumj-core/src/main/java/org/ethereum/datasource/leveldb/LevelDbDataSource.java
AFAIK this is violation of the LGPL (ethereumj) license because you didn't mention that java-tron has been derived from the ethereumj project.
You might want to get your licensing right. Copying someones work without giving them proper credits is at leased considered very bad practice in the open source community (ignoring any legal aspects of this because I'm not a lawyer).
