I tried debugging the ant task standalone running against the
pregenerated jar, and in this case the code ran fine, It seems like i
only have problems when the jar is generated in the same process as when
i tried to load.

Hello Dave,
In addition to what Stefan noted, could you also tell us which
specific version of Java 17 this is? The output from "java -version"
command would be useful.

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
[genSchema] Caused by: java.util.zip.ZipException: ZipFile invalid LOC
header (bad signature)
The OpenJDK folks have been adding additional checks inside the zip
package which may reject archives it has been able to read before. This
has found at least one bug in Ant's zip code[1] which looks unrelated to
your exception (and has been fixed in 1.10.14).
It may be the case this is another bug inside of Ant's zip package - or
the added checks inside of th JDK are wrong. Any chance you could try
with jdk21 (I've seen they've relaxed/adapted some checks after jdk17)?
Also you may want to check the jar with a different zip tool like unzip
to see whether it emits any warnings. If all else fails, it would be
great if you could provide us with a jar that's been rejected so we can
have a look ourselves.
Cheers
Stefan
