Getting the error while updating GWT 2.5.1 to 2.9.0 and sencha GXT 3.1.1 to 4.1

Question

Quick question. Getting below error:

Loading inherited module 'com.sencha.gxt.ui.GXT'
     [java]          Loading inherited module 'com.sencha.gxt.data.Data'
     [java]             Loading inherited module 'com.sencha.gxt.core.Core'
     [java]                [ERROR] Line 107: Value 'ie8' in not a valid value for property 'user.agent'

using GWT 2.9.0, Sencha GXT 4.1 and Java11. So, if any one can help me figuring out, how do I resolve this error?
