Because you caninstallmultiple jdks in time,and you are switching among them via alternatives.
The alternatives already covers jre/sdk dir, jcm exports dirs and all jre/jdk binaries llike java 
(and its slaves) or javac (and its slaves)


So unless you wont to have /usr/lib{,64}/some-sepcific-jdk-version1-jni 
/usr/lib{,64}/some-sepcific-jdk-version2-jni and so on, you have to control thos elinks in same way 
as bianries.

Maybe solution may be to have those /usr/lib{,64}/some-sepcific-jdk-version1-jni ... and have 
master switching link of /usr/lib{,64}/jni pointing to right (via alternatives selected) 
/usr/lib{,64}/some-sepcific-jdk-version1-jni
