The Weld Probe JAR seems to include these dependencies in it (for the UI, confirmed by inspecting https://github.com/weld/core/tree/master/probe/core/src/main/client):

• D3 https://github.com/d3/d3/blob/master/LICENSE
• Font Awesome https://fontawesome.com/license
• Bootstrap https://github.com/twbs/bootstrap/blob/v3.3.1/LICENSE
• Ember JS https://github.com/emberjs/ember.js/blob/master/LICENSE
• Handlebars https://github.com/wycats/handlebars.js/blob/master/LICENSE
• Highlight https://github.com/isagalaev/highlight.js/blob/8.9.1/LICENSE
• Jquery https://github.com/jquery/jquery/blob/2.2.1/LICENSE.txt
• Moment https://github.com/moment/momentjs.com/blob/master/LICENSE

None of these are Apache Licensed, yet the only license file shipped with the Probe JAR is the Apache License. Weld is out of compliance with all of these licenses since it does not replicate these licenses in its distribution of Weld Probe & these other products.
