jacocoagent.jar not overridden after upgrade

[WNJStudio]

Environment:

VS Code Version: 1.102.0-insider
Extension Version: from vscode java test 0.43.0 -> 0.43.1
JDK Type & Version: 24
OS Type & Version: windows
Step to Reproduce:

install version 0.43.0 of the Extension
upgrade the extension to versoin 0.43.1

Expected Behavior:
{extensionpath}/server/jacocoagent.jar should be updated from version 0,8.12.xxxxx to 0.8.13.xxxx

Actual Behavior:

vscode-java-test/scripts/buildJdtlsExt.js

Line 82 in bae1928

if (!fs.existsSync(jacocoAgentPath)) {

from the scripts it seems that when upgrading since the jar was present since last version it's not being overridden, causing a version mismatch and therefore causing code coverage not work with java 24

Workaround:
Uninstall the extension and install it clean

Hi WNJStudio, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

The built‐in jacocoagent.jar isn’t picked up if it already exists in your extension folder. You can work around or avoid the mismatch as follows:

• Manually remove the old agent and reload

• Delete {home}/.vscode/extensions/vscjava.vscode-java-test-0.43.1/server/jacocoagent.jar, then restart VS Code. The new 0.8.13.xxxx jar will be copied.

• Use the project’s own Jacoco agent (no embedded jar)

• Try the pre-release that falls back to your project’s jacocoagent.jar: see "Run Test with coverage" doesn't work: "Could not find or load main class" #1714 (comment)

• Full reinstall (uninstall + install) also forces the update.
