> Affects Versions: 4.8.1
> Reporter: Uwe Schindler
> Assignee: Uwe Schindler
> Labels: Java8
> Fix For: 4.8.2, 4.9, 5.0

>
> When compiling the codecs with Java 8 update 20 (coming soon), we fail: The
> constructors initialize a final closeable field inside a try block, which
> makes the field possibly undefined in the finally block.
> Previous Java versions somehow did not detect this bug, but it is a real one.
> Final fields must be initialized before they are used. Earlier compilers did
> not detect this bug, but I think it is not buggy, because IOUtils can handle
> null.
