APAR status
Closed as program error.

Error description
Running a stress test after applying PQ49167 on 3.5.4 under JPro
be, and from Visual Inspection, it appears that we have
introduced a char[] to String conversion when calling the _jspx_
writeString( JspWriter jOut, char[] staticContent ) that didn't
exist before.   From the JProbe output, when this method is call
ed, we spent about 71% of the time in this method to the new
String( char[] ).
Development  is requesting a revisit of PQ49167 for possible per
formance improvements.

Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server site users      *
*                 where the character encoding (charset) of    *
*                 the client (browser) differs from that       *
*                 of the server.                               *
****************************************************************
* PROBLEM DESCRIPTION: It's possible the wrong charset         *
*                      (encoding) could be used to generate    *
*                      JSP output.                             *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The way the static JSP content was being converted to Strings
was not taking into account client charset encoding.  If
client encoding and server encoding differed then the output
could be displayed incorrectly.
Problem conclusion
Changed the generated Java to not convert static JSP content
to a String before sending to client.
