Polish formatting

[pderop]

Expected behavior

Basic formatting should be used, like a space after a try, or after comma

Actual behavior

in the MP codec, we have some code like:

return testHighNumberChunks(ctx,true, true);

or

try(RandomAccessFile accessFile = new RandomAccessFile(dest, "rw");

Also, javadoc should be reviewed and the following comment should be removed.

Steps to reproduce

Minimal yet complete reproducer code (or URL to code)
