I have a project made with JDK 7 with ojdbc6 working normally. After update for JDK 8 (and recreate jar), the project raise the error "Invalid number format for port number" on connect to database. The old jar still working. Nothing was altered in source. I try update for ojdbc7, without success. The connection string is in format jdbc:oracle:thin:@ip:1521:db
Any suggestions?
