As Hermann noted the error message indicates that you're using JDK 7 for tWAS, so please update to JDK 8. I'd also encourage your to update to the latest fixpack as well.
That said, I'm going to suggest that you not update to tWAS v9.x, unless you have need for Java 7 EE.
This because both tWAS v8.5.5 and v 9.05 are supported until 2030,
https://www.ibm.com/cloud/blog/announcements/ibm-websphere-2030-support-announcement
and one of the primary reasons for extending support for both versions was so that clients didn't have to invest in migration from v8.5.5 to v9.05 in order to continue to be supported.
Instead we're recommending that clients invest their time and effort in migration from tWAS to Liberty since Liberty is a cloud appropriate application server and it provides additional API's, e.g. Java 8 EE/Jakarata 8 EE, which aren't available in tWAS, as well as support for Java 11 SE (as well as later versions of Java SE). Anticipating the obvious question, there are no plans to deliver Java 8 EE in tWAS, this because Java 8 EE (as well as Java9 EE) is focused on microservices, and it doesn't make sense to run a microservice application in a monolithic application server such as tWAS.
Additional there are no plans to update the Java SE level in tWAS beyond Java 8 SE, this because of architectural differences in Java 9 SE and above, which are incompatible with the tWAS architecture.

Subject: not possibile to run an app on webshere 8.5
Hi all I new with Websphere and I tried to do the following example:
https://developer.ibm.com/recipes/tutorials/deploying-vaadin-8-8-2-on-websphere-application-server-8-5-5-15-traditional/#r_overview
But I get:
I've checked that the vm in the eclipse.ini file is from IBM and it is 8 , checked that the VM used to compile with maven is the same, but eclipse still tell me that the server use SDK 7;
Could please some one help me?? really thanks;
I attacched some other screen shot in order to see the SDK used in other process of development:
1. Maven
2.run time enviroment
