Encountered exception during PrintParameters communication

[GoogleCodeExporter]

JavaSnoop 1.0 RC4, Win7 x86, JDK 1.6.0_21 (32-bit), starting using startup.bat.

What steps will reproduce the problem?
1. Launch jEdit
2. Launch JavaSnoop, attach to jedit.jar process
3. Add function hook on 
org.gjt.sp.jedit.search.SearchAndReplace.setSearchString (or any function)
4. Enable [x] Print parameters and [x] ...to console options for hook
5. Trigger function by running a search in jEdit. Observe [SNOOP ERROR] as 
below.

This seems to happen regardless of what I try to use JavaSnoop on (tried 
applets too).

Having trouble replicating. Can you load a console for the jEdit process and 
show the output of that and the output from the startup.bat cmd window?

The steps for showing a console for every Java program in Windows:
1. Open up Control Panel
2. Open up Java settings
3. Go to "Advanced"
4. Go to "Java console"
5. Enable "Show console"

It's working on Vista/32-bit/1.6.0_21. Also, did you start jEdit first or 
JavaSnoop? JavaSnoop should always be started first (it turns off security). 
Here's my output from a quick test:

[2010/08/01 22:44:24] Print parameter request from: 
org.gjt.sp.jedit.search.SearchAndReplace.setSearchString(String): 
Parameter 1 (type: String): test

Reproduced with the patient help of submitter Hubert Seiwert. Fixed in RC5 
which was just released. RC10 will be 1.0 unless a happy place is found before 
then.
