Re: FW: Re: FW: [Wrapper-user] libwrapper.so on A64 part II

[Leif M. <le...@ta...>]

John and I have been talking off line but wanted to post on the list as 
well.
After playing with trying to get a 64-bit native version of the Wrapper 
working for a while,
I had realized that the JVM being run was 32-bit.   I tried the regular 
32-bit version of
the Wrapper with that JVM and it works file out of the box.

The 64-bit version of the Wrapper does not of course work with the 
32-bit JVM.  But
I have not yet had the opportunity to try it with a 64-bit JVM on the 
A64 system.  It is
building however.

Cheers,
Leif
