But javac also supports cross-compilā€ ing, where classes are compiled against a bootstrap and extension classes of a different Java platform implementation. This option is disabled by default but can be enabled on the Java > Compiler > Errors/Warnings preference page:

In addition, you can also insert inferred type arguments of a See the DatagramChannel class specification for more information. Typically, the distinction is of no consequence; and for compatibility, it is preferred that the identity and number of returned methods match Java SE 7 as closely as possible.

It does not actually remove the protocol handler - applications that use this protocol will continue to work, but its presence is no longer required. If any processors generate any new source files, another round of annotation processing will occur: any newly generated source files will be scanned, and the annotations processed as before.

Cross-Compilation Options By default, classes are compiled against the bootstrap and extension classes of the platform that javac shipped with. How do I get more information when I get java.lang.reflect.InvocationTargetException? The example above works, because our default user class path happens to be the directory containing the package directory. But javac also supports cross-compiling, where classes are compiled against a bootstrap and extension classes of a different Java platform implementation.

Class.getMethod and Class.getMethods were not updated with the 8 release to match the new inheritance definition (both may return non-inherited superinterface methods).
