Added `DirectMethodBuilder::withFlags` too, for consistency.

Gatherers are designed to be reusable, Streams not. So having a Gatherer which
isn't reusable would be a bit of a non-starter I'm afraid. Or perhaps I
misunderstood?
Personally, when I want to concat m
Please review this cleanup PR which makes `ZipFile.Source.initCEN` not include
the 22-byte trailing`END` header when reading the `CEN` section of the ZIP file.
The reading of the END header was probably brought over from native code with

Hi Kim,
Thanks for the details.
So to summarize:
- Kim is saying that "Interpretation B" is how it actually works.
- Viktor is saying that "Interpretation A" is how it actually works.
Do I have that right?

P.S. Viktor: my apologies for misspelling your name before

Do you think we need a parallel declaration in `DirectMethodBuilder`? Though
that one won't b

This PR reduces number of classes loaded on a minimal lambda bootstrapping test
by 4 by avoiding the need to pull in some AccessFlag classes.

Commit messages:
- Add withFlag(int) to DFB for consistency
- Avoid loading AccessFlag by providing overrides
Changes: https://git.openjd
The string concatenation of the java.base module is implemented using
StringBuilder. By providing a series of concat methods in StringConcatHelper,
it is used in the java.lang package to replace string concatenation.
These concat methods can also be exposed through JLA for use by other packages,
