[Dspace-tech] Problem with upgrading from DSpace 1.6.2 to DSpace 1.7.1
George Stanley Kozak
Hi…
I am upgrading (in Test) from DSpace 1.6.2 to DSpace 1.7.1. Everything has worked perfectly until I came to the step:
/dspace/bin/dspace index-init
When I try to execute that, I get:
Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:621)

at java.lang.ClassLoader.loadClass(ClassLoader.java:252)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)
I can’t figure this out. All of the Class paths seem fine. Anyone have any suggestions?

You are using an old version of Java; older than the version that the code was compiled under.

you used a newer version to compile your code with than you use in runtime.
You can check which versions you are using per default with
javac -version
java -version
Hope that helps

Thank you, Ralph:
That led me to my problem. I have Jdk 1.6.0 installed, but my server has jdk 1.5 installed as the default (and our IT group won’t allow me to replace it).
My paths were such that when I tried to execute java, it was going to the old one instead of the newer one.
I will fix that. Thanks, again!
