Summary: Jelly scripting in maven.xml
Type: Bug
Status: Assigned
Priority: Critical
Time Spent: Unknown
Remaining: Unknown
Project: maven
Components:
jelly-integ
Fix Fors:
1.1
Versions:
1.0-beta-9
Assignee: Jason van Zyl
Reporter: Incze Lajos
Created: Wed, 5 Mar 2003 5:23 PM

Environment: RedHat 8.0 all patches, j2sdk-1.4.1_01, maven HEAD
Description:
Jelly scripting in maven.xml is somehow not safe. The script
attached sets the namlenX vairable in various ways, and then
tries to use the values. The variable is set, the value is
correct, but using it as parameter in a call like
somestring.substring(namlenX) sometimes misteriously fails.
The attached script tries to be self explaining and comes
from a real life example.
When run the attached script namlen1, namlen2 does not work,
namlen3 work. A piece of a run shows this output:

etc.
===============================
The worrst of all, that seemingly the usability of the namleX
depends on HOW (??) it was set.
