This path (share/OpenCV/java(JAR_INSTALL_DIR)) is hard coded in the 
modules/java/CMakeLists.txt file.

I expect that the FindJNI.cmake from the CMake Modules detects something 
from the host system or you have add Java to your sysroot. Have you 
check the output of the CMake configuration for the ANT_EXECUTABLE and 
JNI_INCLUDE_DIRS.

In any case the opencv recipe is not deterministic in case of the Java 
support.

You could try to add "-DBUILD_FAT_JAVA_LIB=OFF" to the EXTRA_OECMAKE but 
this doesn't disable the whole Java support.
