An Apache Santuario library version upgrade, used by the javax.xml.crypto.* packages, introduces a behavioral change where a new Base64 encoder uses "\r\n" as end-of-line terminator. By default, XML signatures signed using API calls form the javax.xml.crypto.dsig package includes the escaped '\r' character, encoded as "
" or "
".

A new `com.sun.org.apache.xml.internal.security.ignoreLineBreaks` system property may be set to a value of "true" if an application is unable to handle the encoded output data changes where "
" or "
" get appended to new lines in encoding operations. The effect of this property is to not include the carriage return character in base64-encoded fields in XML signature generated by calls to the javax.xml.crypto.* packages.
