Re-interrupt the thread in the generated code

[feliksik]

Otherwise the client has to check for the type (InterruptedException) of the cause of the thrown exception.

Fixes #4380

• Read the contribution guidelines.
• If contributing template-only or documentation-only changes which will change sample output, build the project before.
• Run the shell script(s) under ./bin/ (or Windows batch scripts under.\bin\windows) to update Petstore samples related to your fix. This is important, as CI jobs will verify all generator outputs of your HEAD commit, and these must match the expectations made by your contribution. You only need to run ./bin/{LANG}-petstore.sh, ./bin/openapi3/{LANG}-petstore.sh if updating the code or mustache templates for a language ({LANG}) (e.g. php, ruby, python, etc).
• File the PR against the correct branch: master, 4.3.x, 5.0.x. Default: master.
• Copy the technical committee to review the pull request if your PR is targeting a particular programming language.

Note that I didn't commit the output of running the ./bin/ scripts... it seemed to create a much larger diff than I expected, that I'm not sure it's doing the right thing.

Please instead run ./bin/java-petstore-all.sh to update the Java samples.

Looks good.

I'll admit I had not known about the need to re-interrupt the thread when catching an InterruptedException, but reading about Java Thread Primitives makes it seem like this is exactly what we need to do.

Thanks for putting this together!

Updated samples via bb86345. All tests passed.

@wing328 ah thanks for pointing this out; I should have used my private email address, but that's ok.
