Java: Some JavadocTag line numbers are wrong

[Marcono1234]

Description of the issue
QL reports wrong line numbers for some JavadocTags.
Example query for LGTM demo projects:

import java

from JavadocTag a, JavadocTag b, Location locA, Location locB
where
  a != b
  and a.getParent() = b.getParent()
  and locA = a.getLocation()
  and locB = b.getLocation()
  and locA.getStartLine() = locB.getStartLine()
select a, b, a.getText(), b.getText(),
  locA.getEndLine(), locB.getEndLine(),
  locA.getStartColumn(), locB.getStartColumn(),
  locA.getEndColumn(),locB.getEndColumn()

Note how these tags should be in the same line, but actually represent tags in different lines.
