Aleksandr Mashchenko commented on WW-4919:
------------------------------------------
Case 1:
You have 1 properties file _message_ru.properties_ with malformed encoding.
Requesting ru locale you get
{{WARN org.apache.struts2.util.TextProviderHelper - The first TextProvider in
the ValueStack (com.opensymphony.xwork2.ActionSupport) could not locate the
message resource with key 'some'
WARN org.apache.struts2.util.TextProviderHelper - The default value expression
'some' was evaluated and did not match a property. The literal value 'some'
will be used.}}
This warning can be improved but at least it is something in the logs.
Case 2:
You have 2 properties file _message.properties_ and _message_ru.properties._
Where _ru has malformed encoding. Requesting ru locale you get value from
_message.properties_ file w/o any warning in logs, because java silently
fallbacks to default property.
> The load of properties file doesnt show the Exception obtained if exist a
> problem with Unicode character
