> Fix flaky GridFileDeploymentSelfTest
> ------------------------------------

> Key: IGNITE-28863
> URL: https://issues.apache.org/jira/browse/IGNITE-28863
> Project: Ignite
> Issue Type: Test
> Reporter: Dmitry Werner
> Assignee: Dmitry Werner
> Priority: Minor
> Labels: MakeTeamcityGreenAgain, ise

> *Root Cause*
> All 7 GridFileDeploymentSelfTest failures stem from a duplicate entry in
> deployfile-bad-signed.jar.
> The pom.xml build script intentionally creates a corrupted JAR for testing
> bad signature verification:
> 1. Copies `GridUriDeploymentTestTask11.class` under the name
> `GridUriDeploymentTestWithNameTask11.class` (bytecode contains `this_class =
> GridUriDeploymentTestTask11` → mismatch with filename)
> 2. Packs this corrupted class into JAR, signs it, then updates the JAR with
> the correct class:
> {code:java}
> <zip destfile="...${bad-signed.jar}" basedir=".../target/classes/"
> includes=".../GridUriDeploymentTestWithNameTask11.class" update="yes"
> />{code}
> The problem: `ant zip update="yes"` behavior changed in Ant 1.9+. Instead of
> replacing an existing entry, it appends a duplicate at the end of the
> archive. The JAR now contains two entries with the same name:
> - First entry (corrupted, `this_class = GridUriDeploymentTestTask11`) —
> loaded by `URLClassLoader`
> - Second entry (correct, `this_class = GridUriDeploymentTestWithNameTask11`)
> — never reached
> On JDK 17, `URLClassLoader.findClass()` loads the first (corrupted) entry →
> JVM throws `NoClassDefFoundError: wrong name`. This crashes the
> `grid-uri-scanner` thread, stopping all subsequent deployments. All
> `checkTask()` assertions fail with `findResource() == null`.
> {code:java}

> The same issue exists for `bad-signed-deployfile.gar` with

> *Fix*
> Replace `ant zip update="yes"` with the standard unzip → copy → zip pattern
> that works reliably across all Ant versions:
> {code:java}
> <unzip src=".../${bad-signed.jar}" dest="${basedir}/target/file_tmp/zipfix"
> />
> <copy
> file="${basedir}/target/classes/.../GridUriDeploymentTestWithNameTask11.class"
> todir="${basedir}/target/file_tmp/zipfix/..." overwrite="yes" />
> <delete file=".../${bad-signed.jar}" />
> <zip destfile=".../${bad-signed.jar}"
> basedir="${basedir}/target/file_tmp/zipfix" />{code}
> Applied to both `deployfile-bad-signed.jar` and `bad-signed-deployfile.gar`.
