[Vtd-xml-users] possible bug, BinaryExpr.compStringNodeSet(BinaryExpr.java:364) ...

[Paul T. <pt...@gm...>]

Hello, while using v.1.9 (and actually, i believe it's a bug in prior
versions dating back to 1.5)
i'm getting the stack trace below.

I've attached a simple unit test that emulates this behaviour.
Within my unit test, if you substitute "FAILING_CODE" with "PASSING_CODE"
on line 23, the error doesn't occur.

As near as i can tell, it's got something to do w/ the "bean" element
that is directly beneath a bean element that contains the "&"
symbol, as is the case w/ the "AIR" bean"

if the attachment doesn't make it, i can simply inline the class, let me know

thoughts?
