On a WAAE server, there are two JREs installed under the WAAE directory tree. One is 32-bit (JRE_WA), and one is 64-bit (JRE64_WA). Is it possible to update these JREs to a newer version without upgrading the whole application?
Each WAAE service pack is build and QA'd against the JRE versions installed with that service pack. Upgrading these JREs outside of a service pack update is not supported.
