Which actually means that you installed Oracle with different java VM. Usually Oracle is installed with its own VM, but you can point it to other VM during installation. Check which VM was set during Oracle installation.

Usual problem with dbca, netca, emca and other java-based tools in Oracle. These scripts are created during installation, and the text of the scripts is tied to the java VM used by Oracle during install. If you want to switch to different VM, you have only 2 solutions: 1. reinstall software.
2. Manually modify scripts (I did it once but wouldn't recommend).

One more hint: there is a bug related to java VM referencing in 9.2, on some computers the reference is not correct. The workaround is to set environment variables ORACLE_BASE and ORACLE_HOME before installation and set the to different directories. Which actually means that you can't have inventory in ORACLE_HOME.
