Under some unusual conditions, JRE uninstallation isn't complete and leaving some registry keys in the registry although all the binaries and directories have been removed. deployHelper should take this situation into account and should sanity check the existence of the file pointed to by the registry key before declaring the JRE is installed.

To reproduce this problem, I'm suggesting setting up some dummy registry keys such as:
HKLM\SOFTWARE\JavaSoft\Java Runtime Environment\1.4.2_07
with all the appropriate subkeys: JavaHome, MicroVersion, RuntimLib
but not actually installing the JRE.
