XML signature containing a line break is generated in JBoss EAP 7.4.9+ and 8.0.x

Issue

Our application creates XML signatures in the way explained in Java SE 8 document XML Digital Signature API. The behavior of XML signature has changed between JBoss EAP 7.4.8 and 7.4.9, and line breaks has been included as the follows. Is there any workaround for avoiding the addition of the line breaks?

JBoss EAP 7.4.8 or earlier
