@vy, I completely overcomplicated things earlier by assuming parent POM
overrides, and my Docker setup completely collapsed on me and messed up the
results.
I started from my local installation, I installed Java 8 locally on my Mac
and followed your exact steps manually.
this what i observed:
**1. Created a reproduction project:**
I set up a minimal Gradle project using Java Toolchain 8, enabled
`-Xlint:classfile` and `-Werror`, and added a class calling
`PropertiesUtil.getProperties()` as Piotr suggested.
**2. Verified against 2.26.0:**
I pointed the project to `2.26.0`. The build failed with the "class file not
found" warning:
```text
> Task :compileJava FAILED
/Users/ramanathan/.m2/repository/org/apache/logging/log4j/log4j-api/2.26.0/log4j-api-2.26.0.jar(org/apache/logging/log4j/util/PropertiesUtil.class):
warning: Cannot find annotation method 'value()' in type
'aQute.bnd.annotation.spi.ServiceConsumer': class file for
aQute.bnd.annotation.spi.ServiceConsumer not found
error: warnings found and -Werror specified
1 error
3 warnings
```
**3. Verified against unpatched 2.27.0-SNAPSHOT (which pulls 7.1.0):**
I pointed the project to the current `2.x` branch. The build failed and
reproduced the exact Java 17 bytecode error reported by users:
```text
> Task :compileJava FAILED
/Users/ramanathan/.m2/repository/org/apache/logging/log4j/log4j-api/2.27.0-SNAPSHOT/log4j-api-2.27.0-SNAPSHOT.jar(org/apache/logging/log4j/util/PropertiesUtil.class):
warning: Cannot find annotation method 'value()' in type
'aQute.bnd.annotation.spi.ServiceConsumer': bad class file:
/Users/ramanathan/.m2/repository/biz/aQute/bnd/biz.aQute.bnd.annotation/7.1.0/biz.aQute.bnd.annotation-7.1.0.jar(aQute/bnd/annotation/spi/ServiceConsumer.class)
class file has wrong version 61.0, should be 52.0
Please remove or make sure it appears in the correct subdirectory of the
classpath.
error: warnings found and -Werror specified
1 error
3 warnings
```
**4. Verified the fix on patched 2.27.0-SNAPSHOT:**
I bumped `<bnd.annotation.version>` to **`7.2.3`** in
`log4j-parent/pom.xml`, ran `./mvnw clean install` to install it locally, and
refreshed the Gradle cache. The build passed perfectly:
```text
> Task :compileJava
BUILD SUCCESSFUL in 2s
