HI folks, we have an odd situation where we have an ant build that
generates a jar file that includes a resource bundle property file using
<jar>, later in the same build a custom ant task is executed, which
loads that class from the classpath, and tries to read that bundle
file, and fails with

My guess was, for some reason that jar file wasn't completely written
and/or closed by the time the custom task is run. To test, before
running the custom test, i do this
<copy file="${snapshots.dir}/opc-i18n.jar"
tofile="${snapshots.dir}/opc-i18nX.jar"/>
<copy file="${snapshots.dir}/opc-i18nX.jar"
tofile="${snapshots.dir}/opc-i18n.jar"/>
both copies seem to go fine, kind of ruling out the open part. and when
i manually open the copied jar after the build, it seems fine (no bad
LOC header from ui tools). [btw, the original file loads fine in ui
tools too]
If i run the section that uses the jar, without the script that
generates the jar, it works fine.
No use of <parallel> is used.
Anyone have any ideas what could be going on? Or how to debug more?
