== Why is this an issue?
|
|
|
|
The classes in the `sun.*` packages are not part of the official Java API and are not intended for public use. They are internal
|
|
implementation details specific to the Oracle JDK (Java Development Kit). Therefore, their availability, behavior, or compatibility is not
|
|
guaranteed across different Java implementations or versions.
|
|
|
|
Since these classes are not part of the official Java API, they usually lack proper documentation and support. Finding comprehensive and
|
|
up-to-date information about their usage, functionality, and potential limitations can be challenging. This lack of documentation can make
|
|
it difficult to understand how to use these classes correctly.
|
|
|
|
Classes in the `sun.*` packages are often platform-dependent and can vary between different operating systems or Java Virtual Machine (JVM)
|
|
implementations. Relying on these classes may lead to code that works on one platform but fails on others, limiting your code's portability
|
|
and cross-platform compatibility.
