svn commit: r1430079 - in /tomcat/trunk:
java/org/apache/tomcat/util/buf/B2CConverter.java
test/org/apache/tomcat/util/buf/TestB2CConverter.java
Author: markt

New Revision: 1430079
URL: http://svn.apache.org/viewvc?rev=1430079&view=rev
Log:
Fix https://issues.apache.org/bugzilla/show_bug.cgi?id=54248
Need to reset the decoder when the N2C converter is recycled to ensure BOMs are correctly handled for those encodings that require them.
