Yes, validation may have been one issue. Although I made
no substantive changes of which I was aware, it was one of
the ways I could cause the install to hang, and crash tomcat
in the process.
However, the install task hung and crashed tomcat in two
other ways, as well:
a) An exception was thrown when a file was not found
as the servlet was inititializing.
b) An XML parsing exception was thrown when the
XML data file turned out to be ill-formed.
---------------
I had this:
<!DOCTYPE name>
<!ELEMENT ...>
</DOCTYPE>
instead of this:
<!DOCTYPE name
[
<!ELEMENT ...>
]>
