eolivelli opened a new issue, #4777:
URL: https://github.com/apache/bookkeeper/issues/4777
### Description
Branch `branch-4.17` fails to compile after commit 0e1bddd7e5 ([Fix]
ConcurrentLongHashMap throw ArrayIndexOutOfBoundsException, #4771) was
backported to it.
The commit introduces a Java `record` declaration in `ConcurrentLongHashMap`:
```java
private record Table<V>(long[] keys, V[] values, int capacity) { }
```
The `record` keyword requires Java 16+, but on `branch-4.17` the root
`pom.xml` sets:
```xml
<maven.compiler.source>8</maven.compiler.source>
<maven.compiler.target>8</maven.compiler.target>
```
so the file fails to parse.
### Build error
```
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:3.12.1:compile (default-compile)
on project bookkeeper-server: Compilation failure: Compilation failure:
[ERROR] .../ConcurrentLongHashMap.java:[320,29] ';' expected
[ERROR] .../ConcurrentLongHashMap.java:[320,32] illegal start of type
```
### Affected branches
- `branch-4.17` — broken (Java 8 target).
- `master` — not affected (Java 17 target).
### Proposed fix
Replace the record with an equivalent `static final` nested class exposing
`keys()`, `values()` and `capacity()` accessors, preserving the existing call
sites.
