lombok_jar absolute Windows path is joined to extension workdir, breaking JDTLS startup

[cloud0106]

Environment

• OS: Windows
• Extension version: 6.8.25

Description

When lsp.jdtls.settings.lombok_jar is set to an absolute Windows path (as documented in the README), JDTLS fails to start.

Steps to reproduce

1. Set in settings.json:

"lsp": {
  "jdtls": {
    "settings": {
      "lombok_jar": "D:\path\to\lombok-1.18.36.jar"
    }
  }
}

2. Open any Java file.

Actual behavior

The language server resets the connection. The log shows:

initializing server jdtls, id 1: Server reset the connection
-- stderr --
Error opening zip file or JAR manifest missing : <USERPROFILE>/AppData/Local/Zed/extensions/work/java/D:/path/to/lombok-1.18.36.jar

The configured absolute path is concatenated onto the extension workdir instead of being used as-is.

Expected behavior

The configured absolute path is passed to JDTLS as the -javaagent argument without modification.

Root cause

In src/jdtls_server.rs, command() builds the agent argument with current_dir.join(lombok_jar_path). The extension runs as WASM, which uses POSIX path semantics — a Windows drive-qualified path like D:\... is not treated as absolute there, so join() appends it to the workdir. This does not happen on macOS/Linux because POSIX absolute paths start with /.

Also affected

• java_debug_jar — src/debugger.rs uses the same current_dir.join(...) pattern in inject_plugin_into_options().

Workaround

Copy the jar into the extension workdir and reference it with a relative path:

extensions/work/java/lombok/lombok-1.18.36.jar

"lombok_jar": "lombok/lombok-1.18.36.jar"

Suggested fix

Only join the configured path with the workdir when it is relative; detect Windows drive-letter paths (e.g. a leading X:\ or X:/ prefix) and use them as-is.

Thanks for reporting, this issue has been in the code for some time but it never surfaced. I'll work on a fix for it covering both Lombok and the debugger.

@cloud0106 could you test that on Windows?
