Yes, I am certain that the "java6" was added to prefer the java6 runtime
on systems where java5 was also installed, but now it seems to be having
an undesired effect.  So it sounds like we have a bug in the
"javahelper" package as well.

Also, thank you for the information about the cursor CopyDrop.32x32
issue.
