Thank you for the explanation. Places that practice poor technically inadvisable practices are not sufficient rationalization to me. I'm +1 to dropping 1.42 BTW if someone proposes the vote. (Generally you can count me to support dropping anything more than two major releases back)

Why exactly? Running a JDK that is 2 versions back tends to be a rather large faux pas as well. Is there still a platform that 1.5 isn't available for?

be a big mistake. In any case, I tried manually building the jars from source with JDK 1.4.2, and it works fine.

yeah unless we've dropped 1.42 then it should be compiled on 1.42.
So the last build is invalid or we need a vote to drop
1.42 and req
5+

Obviously, I was wrong to refer to this as the scratchpad

the main poi jar.

I'm trying to use 3.0rc2, and I'm trying to use the
scratchpad jar
for the first time.  I'm using JDK 1.4.2.
When I try to compile my code with Ant, I get the following:

bad class file:
...\lib\poi-3.0-rc2-20070329.jar(org/apache/poi/hssf/model/Wor
kbook.clas
s)
class file has wrong version 49.0, should be 48.0 Please
remove or
make sure it appears in the correct subdirectory of the
classpath.
import org.apache.poi.hssf.model.Workbook;
