URL: https://github.com/apache/logging-log4j-kotlin/issues/145
There is a vararg forwarding bug in two Kotlin wrapper APIs, where the
argument array is passed as a single object instead of being spread. This
causes malformed formatted output and loss/distortion of log detail.
**Affected APIs**
1. ContextStack.push(message: String, vararg args: Any?)
2. KotlinLogger.traceEntry(message: String, vararg args: Any?)
**Problem**
Current forwarding passes args without spread, so placeholders are not
expanded as intended.
For example, for ContextStack:
- Input format: user={} action={}
- Input args: alice, login
- Observed output: user=[alice, login] action={}
- Expected output: user=alice action=login
**Reproduction**
Environment used:
- Branch: main
- Commit: b6ab1b9a7cdd37d1faabb7ac62f26193ac9b6a90
- JDK: 17
**Command used:**
./mvnw -pl log4j-api-kotlin -Dtest=VarargForwardingParityTest test
**Observed test failure:**
- expected: <user=alice action=login> but was: <user=[alice, login]
action={}>
