We have been running our application with xalan 2-6-0 fine. When I upgraded
to xalan-2-7-0 I get very strange error in one of my xml to xsl
transformation. The error that gets printed on the console is as follows
file:///C:/opt/eclipse/dummy.xsl; Line #0; Column #0;
java.lang.NullPointerException
There is no dummy.xsl file in the project. Following is the related xml and
xsl code
