[java] LocalVariableCouldBeFinal on 'size' variable in for loop

**Affects PMD Version:** 7.0.0

**Rule:** [LocalVariableCouldBeFinal](https://pmd.github.io/latest/pmd_rules_java_codestyle.html#localvariablecouldbefinal)

**Description:**
The following line causes a LocalVariableCouldBeFinal warning, but this can't be fixed. As "size" can't be declared final.

```java
for (int i = 0, size = loaders.size(); i < size; ++i) {
```
