> 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.
