Clean install of JBDS 3.0 and want to add plugin JD (decompiler), enable feature Preferences -> General -> Capabilities -> Classic Update, then try to add JD as new plugin remote location in update software section gives errors on this file which block further installation:

jbdevstudio/studio/eclipse/features/org.jboss.tools.runtime.feature_1.1.0.v201003100055R-H50-GA/feature.xml

Errors are 2:

1) only one URL tag allowed, it detects more than one

2) no closing FEATURE tag

Fixed by removing the LICENSE line with URL and complete copyright section leaving only this:

<?xml version="1.0" encoding="UTF-8"?>
<feature id="org.jboss.tools.runtime.feature" label="%featureName" version="1.1.0.v201003100055R-H50-GA" provider-name="%providerName">
