In general should be backwards compatible, you can check the official documentation release note and see if there are any abandoned what API, such as you use the abandoned API source

Late development stage, if use 1.7 recommended maintenance and use 1.7, deployment and use 1.7
If you want to compare with the new JDK version to new version, you can try 1.8, online project at present, the majority or 1.8!

If you modify the JDK, there is an error in the IDE, can look at change, can start up, basic no problem if the compiler is normal,
Very upgrade JDK10 and 10 + version is not recommended, in 10 version update content is large, and EE requires a separate configuration, may not be compatible with more
Suggest to use 1.8 give it a try
