Hello,

In order to compile syslog-ng with java, you must have javac (and javah).

Simply replacing javah/c with java is not okay, they are different and not
interchangeable.

You must have JRE to run java based destination which you've installed, but
to compile you must have JDK, which shall contain javah/c.
