Hi,
if you are fast, you can see that jaxen-from-packaged-dom4j fails on
"traditional" Gumps at
<http://gump.covalent.net/log/jaxen-from-packaged-dom4j.html>.
The reason is this:
[javac] Compiling 23 source files to /data/gump/jaxen/target/test-classes
[javac] /data/gump/jaxen/src/java/test/org/jaxen/AddNamespaceTest.java:124: unreported
exception org.jaxen.JaxenException; must be caught or declared to be thrown
[javac] super( expr );
[javac] ^

[javac] reader.setXPathHandler( handler );

[javac] 3 errors
It doesn't fail on Gumpy and I've been trying to find out why. Taking
the very first error, it is the constructor of
class MockXPath extends BaseXPath
with
public MockXPath(String expr) throws SAXPathException
and in src/java/main/org/jaxen/BaseXPath.java we find
protected BaseXPath(String xpathExpr) throws JaxenException
As JaxenException extends SAXPathException this should compile.
Digging deeper, there is another BaseXPath class coming in from
dom4j-full.jar in the packaged dom4j project, JaxenException is there
as well. It seems as if JaxenException didn't extend SAXPathException
in that version.
In "traditional" Gump, <work> elements get appendend to the CLASSPATH
while Gumpy prepends them. So in "traditional" Gump we should pick up
the classes from dom4j-full.jar while Gumpy sees the one from the
<work> entry.
So, should <work> get to the front or the end of the CLASSPATH?
Adding it to the front seems right as long as it doesn't get abused to
point to jars of released versions inside the CVS tree, but I may be
missing a reason why "traditional" Gump works the way it does right
now.
