SV: SV: SV: [jdom-interest] Error in build : trinity

[Per Norrman]

Hi again,

In your original post, there error message was 'trin ity'.
My gut reaction was that this was somehow a thread concurrency
problem; 'ity' is the ending of 'entity' which is a fairly common
word in XML error messages. I suspected a mixup, due to a race
condition or whatever.

Anyway, is this a consistent error message, i.e. does it always say
'trin ity' when it fails?

Does each request use its own XMLParser instance?

When the error occurs, have you tried logging the request content?
