javah tool from the JDK.
The tool has been superseded by superior functionality in javac, added in JDK 8 (JDK-7150368). This functionality provides the ability to write native header files at the time that Java source code is compiled, thereby eliminating the need for a separate tool.
Focusing on the support provided by
javac eliminates the need to upgrade
javah to support recent new paradigms, such as API access via the
Compiler API in
javax.tools.*, or the new
java.util.spi.ToolProvider SPI added in JDK 9.
Implementing the removal will include removing the affected files from the Mercurial repositories, including documentation files, as well as supporting makefile changes.
Any testing will be limited to verifying the
javah command is
Risks and Assumptions
There are no engineering issues with excising
javah from the JDK,
because the tool is no longer used by JDK, or when building the JDK.
Users have been warned of the pending removal since JDK 9,
in which a warning is generated each time the
javah tool is invoked.
There are no direct JDK dependences on the
javah tool. Externally,
there are some derivatives of
javah, such as the Ant
but just as users of the
javah command are recommended to
javac -h, so too are users of these dependences are recommended to
use instead the corresponding support provided for
