<project xmlns:ac="antlib:net.sf.antcontrib">
<ac:for param="i" begin="0" end="1">
<sequential>
<echo>i is @{i}</echo>
</sequential>
</ac:for>
</project>
With begin=end=1 you will get the error message
build.xml:2: end <= begin, step needs to be < 0
So I see two possibilities:
1) the exceptional 1-jvm-case
<macrodef name="doit">
<attribute name="param"/>
...
<ac:if>
<equals arg1="${end}" "1"/>
<ac:then> <doit param="1"/> </>
<ac:else>
<ac:for ...> <doit param="@{i}"/>
2) NullObject
Maybe your <sequential> implementation could deal with the value '0' (and do
nothing)
