9.0.1.9 upgrade

I'm testing a 9.0.1.9 upgrade from 9.0.0.x on Win2003 32-bit.

All seems to be going well, until the upgrade hits a snag in the install of core technology. Here's the tail end of the install.log. The message, ldifgen bootstrap failed appears to be an issue with the java.security file. But I've already ran all my tests with BouncyCastle and they came up fine. There's a KB article 558556 which addresses this, but still I've reviewed the java.security file and it appears OK.
Has anyone else seen this issue before? I've also got Lawson working on this issue but no resolution yet.
