507f80617d [bug] Templates via classpath (#5164)
* Fixes issue with templates loading via classpath

The templating engines were originally written to load templates via the
classpath, but this functionality was blocked by file-only checks
further up the stack. This loosens those file-only checks, allowing
files and relatively imported files to be included via classpath.

* [docs] Add details about classpath-level templates

* [feat][maven] templateResourcePath for template on classpath
  - NOTE templateResourcePath is not needed for gradle, as it accepts
    a string for the target template directory, which supports classpath

22c6c0ca68 [core] Extracting recommendations to validation framework (#4979)
* [core] Extracting recommendations to validation framework

This is work to extract recommendation logic out of the CLI validate command
into a shared evaluation instance which can be used elsewhere (such as Gradle,
or the Online tool).

For now, these validations are in addition to those provided by swagger-parser and
are only the following recommendations:

* Apache/Nginx warning that header values with underscore are dropped by default
* Unused models/schemas
* Use of properties with oneOf, which is ambiguous in OpenAPI Specification

I've allowed for disabling recommendations via System properties, since this is
something that has been requested a few times by users. System properties in this
commit include:

* openapi.generator.rule.recommendations=false
  - Allows for disabling recommendations completely. This wouldn't include all warnings
    and errors, only those we deem to be suggestions
* openapi.generator.rule.apache-nginx-underscore=false
  - Allows for disabling the Apache/Nginx warning when header names have underscore
  - This is a legacy CGI configuration, and doesn't affect all web servers
* openapi.generator.rule.oneof-properties-ambiguity=false
  - We support this functionality, but the specification may not intend for it
  - This is more to reduce noise
* openapi.generator.rule.unused-schemas=false
  - We will warn when a schema is not referenced outside of Components, which
    users have requested to be able to turn off
* openapi.generator.rule.anti-patterns.uri-unexpected-body=false

* Move recommendation/validations to oas package and add javadoc comments

* Refactor and test recommendation validations

* Refactor validation function signatures to return explicit state rather than boolean

* Add operation recommendation for GET/HEAD w/body

15345e1620 [python] Cleanup ThreadPool with atexit rather than __del__ (#5094)
* [python] Cleanup ThreadPool with atexit rather than __del__

This removes the `__del__` function from the generated Python client,
and replaces it with a `cleanup` function. When a ThreadPool is created,
the cleanup function is registered with the `atexit` module.

This fixes #5093, where the API client could hang indefinitely at
garbage collection.

c9ec084418 🐛 Fixing some issues with threading and NPE (#5107)
* 🐛 Fixing some issues with threading and NPE

After running Sonar on the master branch, some major analysis
opportunities were displayed.

This fixes the use of SimpleDateFormat stored as static fields.
SimpleDateFormat is not thread-safe, and may retain data across threads.
While there's no indicator that this has caused any issues (these are
mostly used for example code), we should follow these best practices.

This also fixes a handful of NPE and other minor issues such as
comparing Boolean.TRUE to strings and no wrapping some closeables in
try-with-resources.

* Quiet batch mode in sonar.yml

b77bffeae1 Typescript axios: remove use of btoa (#5098)
btoa (binary to ascii), is a javascript function to base64 encode a
string.

Axios is usable both from node and from the browser. But the btoa
function is available only in the browser.

This meant that any client that used basic auth was broken in node.
Axios has its own method of encoding basic auth credentials. This method
works in both the browser and node.
https://github.com/axios/axios/blame/v0.19.2/README.md#L318

By using this method, the generated client works in node and in the
browser.

This solves this comment on this issue.

* [test] Removes jmockit in favor of mockito

We use mockito in many tests. This removes jmockit which is run as a
javaagent in favor of Mockito which is not.

This work is in preparation for applying some static analysis tools,
while evaluating others such as Jacoco. I'm also look at ways to improve
build times while also decreasing "ramp up time" for contributions from
the community. Reducing the number of mock frameworks and dependencies
is a step toward that goal.
