Details:

Hello,

I compiled 3.8.1 from source in March 2014 on a fedora-20 x86_64 platform; at
this time libjvm.so full path was
/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.60-2.4.5.1.fc20.x86_64/jre/lib/amd64/server/libjvm.so


By upgrading the system, this file is now 
/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.60-2.4.7.4.fc20.x86_64/jre/lib/amd64/server/libjvm.so

So any java command result in a failure as the lib can not be loaded. 

During compilation, I set the environment variable JAVA_HOME to
/usr/lib/jvm/java-1.7.0-openjdk, which is itself a link to 
/etc/alternatives/java_sdk_1.7.0_openjdk

It seems that this liknk was followed up to the end while building the Java
interface; now the jvm lib has moved. 

I tried to set JAVA_HOME to
/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.60-2.4.7.4.fc20.x86_64, but this didn't
solve the issue. 

Would it be possible to add some fallback mechanism in order to try
alternatives path for this lib ?

Regards

Pascal
