Customer gets the following page fault when using the Symantec JIT 3.0 to be
shipped with JDK 1.1.6 on win32

Happens with all the 3.0 JIT builds we have tried.
Doesn't happen without JIT, and did not happen with previous JIT V2.0 that
was available for JDK 1.1.5

Here's the technical info we have

The app is always trying to make a network connection at the time of the
crash ..

RE caused an invalid page fault in
module KERNEL32.DLL at 016f:bff79ff4.

   - it happens every time, under both 95 and NT
   - the crash is always at the same place in symcjit, but our java
     code is in one of two places (see below, in CastanetRequest)
   - it happens with the standard java.exe. doesn't make sense
     to try our own executable yet.

Here is the assembly surrounding the line where the fault occurs:

01F09B06 51 push ecx
01F09B07 55 push ebp
01F09B08 8B CE mov ecx,esi
01F09B0A E8 E1 C6 FF FF call 01F061F0
01F09B0F 57 push edi

01F09B22 8D 04 80 lea eax,dword ptr [eax+eax*4]
01F09B25 8D 04 82 lea eax,dword ptr [edx+eax*4]

the crash occurs here:
