I have installed JRE7 on AIX 7.1. A customized plugin is required to load libjvm.so from JRE7. But I am getting the following error -

Resolved - The problem was that <JAVA_HOME>/lib/ppc was not present in the Library path. Due to this the library libnio.so was not being searched.

but another question popped up is that, why this was working in JRE 6, although the libnio.so was present at same location?

When using JRE 6 the LIBPATH was set to the following and it worked.
LIBPATH=$JAVA_HOME/bin:$JAVA_HOME/bin/classic

When using JRE 7 it worked when set it to:
LIBPATH=$JAVA_HOME/bin:$JAVA_HOME/bin/classic:$JAVA_HOME/jre/lib/ppc

I noticed that the location of libnio.so has not changed between JRE 6 and JRE 7. Then the question is what has changed in JRE 7 that necessitates adding this new element to LIBPATH.

Has anyone seen such problem before? Can you please share your thoughts, experiences?
