openjdk8 source miss java_lang_String.h file

Question

I cloned openjdk8u source with mercurial, but found it is missing some files such as java_lang_String.h. Where do I get the files?

Answer 1

It is not "missing". It is not included in the OpenJDK source tree by design. See

• https://bugs.openjdk.java.net/browse/JDK-1221207

If you need this file, you can generate it using the JNI header generator.

• With Java 8 and earlier, use the javah tool.
• With Java 9 and later, you should use javac -h; see https://docs.oracle.com/javase/9/tools/javah.htm#JSWOR687
