New to Java

Hi All

I have 2 machines running RHEL 4.5, one is 64 bit, one is 32 bit VM. The have the same JDK installed on them, but when I issue the command:
"java -version" I get a little different result:

On the 64-bit Linux:
java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b02)
Java HotSpot(TM) Server VM (build 1.5.0_16-b02, mixed mode)

On the 32-bit Linux:
java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b02)
Java HotSpot(TM) Client VM (build 1.5.0_16-b02, mixed mode, sharing)

Almost the same, except for on the 32-bit, there is a "sharing" parameter that shows up.

I'm trying to track down a weird application error that I'm getting, and other than the obvious 32/64 bit thing, the app is exactly the same
on both servers. Just wondering if this "sharing" thing might be responsible, but not being very Java-oriented, I have no answer.

TIA
Rick
