exception handling and DOM parsing

[Andrea Foster <Fo...@telkom.co.za>]

Ok, I don't get this. I was under the impression that if I'm executing
three statements like this
x();
y;
z;

then any exceptions thrown internally in x() will be handled _before_ y
is executed. Where x() is a  parse call to a  Xerces validating DOM
parser. And y is a block of statements that is printing the result of a
timing calculation. And z is a block of statements doing pretty printing
of the DOM tree. For the moment all output is going to System.out

Well look at this:

same code. compiled in jbuilder 4. same input data files:

output when run inside jbuilder:

C:\JBUILDER4\JDK1.3\bin\javaw -classpath
"C:\Development\Java\domtest\classes;C:\JavaStuff\xerces-1_3_1\xerces.jar;C:\JBUILDER4\JDK1.3\demo\jfc\Java2D\Java2Demo.jar;C:\JBUILDER4\JDK1.3\jre\lib\i18n.jar;C:\JBUILDER4\JDK1.3\jre\lib\jaws.jar;C:\JBUILDER4\JDK1.3\jre\lib\rt.jar;C:\JBUILDER4\JDK1.3\jre\lib\sunrsasign.jar;C:\JBUILDER4\JDK1.3\lib\dt.jar;C:\JBUILDER4\JDK1.3\lib\tools.jar"
 domtest.domtestmain 

[y output]
[x exception handler output]
[z output]


output when run from .bat file using jdk1.3:


C:\Development\Java\domtest\classes>set PATH=c:\jdk1.3\bin
C:\Development\Java\domtest\classes>set
CLASSPATH=;c:\javastuff\xerces-1_3_1\xerces.jar;c:\development\java\domtest\classes
C:\Development\Java\domtest\classes>cd c:\development\java\domtest
C:\Development\Java\domtest>java domtest.domtestmain

[x exception handler output][y output]
[z output]


What's going on? Depending on the size of the file parsed in x()
sometimes in jbuilder the [x exception handler output] appears inside [z
output]. Oddly enough the output order appears to stay the same with
jdk1.3 regardless of input (admittedly limited) file size fluctuation.
