rootvector2 opened a new pull request, #412:
URL: https://github.com/apache/commons-beanutils/pull/412
`BeanMap.initialize` introspects the bean with `java.beans.Introspector`
directly and registers every property descriptor, so the `class`
pseudo-property (`Object.getClass`, present on every bean) and `declaringClass`
(`Enum.getDeclaringClass`, on enums) become map entries. `PropertyUtilsBean`
registers
`SuppressPropertiesBeanIntrospector.SUPPRESS_CLASS`/`SUPPRESS_DECLARING_CLASS`
by default to drop exactly these, but `BeanMap` applies no suppression, so `new
BeanMap(bean).get("class")` hands back the bean's `Class` and its class loader,
and `keySet()`/`entrySet()` enumerate that entry to any caller treating the
`BeanMap` as an opaque `Map`. Skip both names in `initialize()`, matching the
`"class".equals(name)` guard already in `BeanUtilsBean.copyProperties`.
Found while auditing which introspection paths honor the default `class`
suppression; `BeanMap` was the one that reintroduces it.
`BeanMapTest.testClassPropertyNotExposed` fails without the runtime change.
Updated the sample key/value arrays that pinned the `class` entry.

AI tool was used to create this pull request, and to what extent did it
contribute?
- [x] Run a successful build using the default
[Maven](https://maven.apache.org/) goal with `mvn`; that's `mvn` on the command
line by itself.
- [x] Write unit tests that match behavioral changes, where the tests fail
if the changes to the runtime are not applied. This may not always be possible,
but it is a best practice.
- [x] Write a pull request description that is detailed enough to understand
what the pull request does, how, and why.
- [x] Each commit in the pull request should have a meaningful subject line
and body. Note that a maintainer may squash commits during the merge process.
