Bug appears with xsltc processor and a pipeline of transformer handlers that are constructed from Templates. The following standalone programs demonstrate the bug,(Chain1.java and Chain2.java). Using the Xalan processor in jwsdp 1.2 ea
b07 the bug does not occur. Using Xsltc in jwsdp 1.2 ea b07 the bug appears.
The bug was found using the Astro App test mode 4; however the two standalone
programs show the bug without need to run astro app.

The Chain1 and Chain2 programs output should be the same for a given processor.
In Xalans case this is true, for Xsltc it is not true. In Xsltc case the output
is not HTML but XML. I have also tested these programs with the latest Xalan
code from 3/25/03 cvs repository, and the bug exists in the latest xsltc as well.

Here is the test procedure to demonstrate the problem:
1. Install jwsdp1.2 (jwsdp-1_2-ea-bin-b07-unix-13_mar_2003.sh) jar files into
  $JAVA_HOME/jre/lib/endorsed directory.
2. setenv JAVA_HOME /files/sqe/javas/j2sdk1.4.1_01
3. set path = ( $JAVA_HOME/bin $path )

Chain1 and Chain2 do the same thing, they just use a different set of JAXP
classes to achieve the same result.

4. javac Chain1.java
5. javac Chain2.java

6. Run Chain1 with Xalan and with Xsltc:
   java -cp "." Chain1 > chain1.out.xalan

   java -Djavax.xml.transform.TransformerFactory=org.apache.xalan.xsltc.trax.Tra
nsformerFactoryImpl -cp "." Chain1 > chain1.out.xsltc

7. Compare output from Chain1 with that of Chain2, the output should be the
   same for each of the processors.

    diff chain1.out.xalan chain2.out.xalan ... for xalan they are same

    diff chain1.out.xsltc chain2.out.xsltc ... not for xsltc

Xsltc has the following diff:
Warning: missing newline at end of file chain1.out.xsltc
Warning: missing newline at end of file chain2.out.xsltc

For xsltc processor, the final output of the chained transformers is NOT
HTML, which it should be. The final output has the xml heading and
<br/> elements. It appears as though the output method (set to HTML) of
the last stylesheet (html.xsl) is not being obeyed with the xsltc processor
while running Chain2 program.

I have attached a jar file (bug.jar) with all of these files as well.
I ran this under j2sdk1.4.1_01 with jar files from jaxp1.2.2 installed from
the jwsdp 1.2ea mentioned above.
