Re: [epp-dev] Can we drop 32bit EPP Packages?

[Lars Vogel <lars.vogel@xxxxxxxxxxx>]

I think it is clear an everyone but just in case: to run a 64 bit
Eclipse you need a 64 bit JVM.

As long as Oracle provides a 32 bit version for the JVM I think we
need to provide also a 32 bit version or Eclipse. Several users I know
of use still a 32 bit JVM.
