Answer 2

Why doesn't NetBeans use the JDK compiler?

Quite simply because Sun's javac is intended to be used for batch-based compilation from the command line of definitively valid files. Whereas NetBeans (and other IDEs) do incremental compilation as you type, and quite often have additional features such as creating classes for invalid files (so you can run methodA if methodB has a syntax error in, etc.).

Different tools for different requirements.

Answer 3

Like Eclipse, Netbeans does not use standard javac so that it can offer incremental compilation and compilation of classes containing methods that have syntax errors.

Unlike Eclipse (which uses its own Eclipse Java Compiler), Netbeans actually uses the internal API of javac for compiling, syntax highlighting, and error detection. This is a nice advantage, in that Netbeans is able to handle all of the latest Java language features and faithfully reproduces any nuances or bugs of javac's behavior.
