Hi Dalibor,

 

Thanks you for the response.  I guess you've been instructed to only answer licensing questions by pointing to the FAQ.

 

Looking at the JNI headers in the OpenJDK distribution, they do include the "Classpath exception" text.  So, I'm going to assume that JNI applications do not fall under the GPL.

 

Is this correct?  Just kidding -- you don't need to answer that. ;-)

 

Thanks again,

Kevin

Does this extend to JNI libraries (that do not reference any OpenJDK code) that are actually linked into the JRE through a dynamic library at runtime?
