TurboVNC 2.1.2 was the last version that supported Java 1.6 on Mac (AKA
"Java for OS X Systems", which I tended to refer to as "Apple Java" to
distinguish it from "Oracle Java.") TurboVNC 2.2.x requires Oracle Java
or OpenJDK.
The Mac TurboVNC Viewer is ultimately looking for a file called
libjli.dylib. It first tries to execute /usr/libexec/java_home to get
the Java home directory, and if successful, the viewer looks for
libjli.dylib under {java_home}/jre/lib/jli/libjli.dylib, then
{java_home}/lib/jli/libjli.dylib, then {java_home}/lib/libjli.dylib. If
java_home doesn't return a sane value, then the viewer looks for
libjli.dylib under /Library/Internet
Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib/jli/libjli.dylib. If
all of the above fail, then you get the infamous JRELoadError.
Hopefully that will help you troubleshoot what's going wrong.
TurboVNC 3.0 will have an embedded JRE, so it won't be necessary to futz
with Java anymore.
