I should be more clear saying that the JVM inside the database probably cannot be upgraded *unless you also upgrade the database version*. The 10g jvmdbmig.sql and some other scripts under $OH/javavm/install are for installing JVM or downgrading it. When you use it to upgrade, you're also upgrading the database. Metalink discussion 505865.994 is the most relevant (can you only upgrade Java from 1.3 to 1.4 in JVM of the database?). Look at the bottom message. Searching for "upgrade jvm" (with quotes) on Metalink shows some other notes. They all seem to indicate that you upgrade JVM while you upgrade the DB. Note:205078.1 has 'upgrading the Java engine only' but that's a wrong quote.
