Steps to reproduce:

1. 

Installed Eclipse 3.1 into the following folder:

  E:\eclipse3.1N20040831_Reproduce_%bug\

or Eclipse 3.0.1 into this folder:

  E:\eclipse3.01%M20040825

or Eclipse 3.0.0 into this folder:

  E:\eclipse%3.0.0

2. 

Then, when running 

  E:\eclipse3.1N20040831_Reproduce_%bug\eclipse\eclipse.exe
    or
  E:\eclipse3.01%M20040825\eclipse\eclipse.exe
    or
  E:\eclipse%3.0.0\eclipse\eclipse.exe

instead of starting Eclipse, I get an alert that reads:

  An error has occurred and could not be logged:
  null
               [ OK ]

Steps to mask error:

1. 

As above, then rename the install folder to remove the '%', and the problem goes
away. 

Is this a bug? Or a 'best-practices'/'why would you use a percent sign in a
folder name?' Is eclipse trying to resolve the chars following the % as a
hexcode, such as %20 = space?

;-)

To test the above question, I tried:

  E:\eclipse%203.0.0\eclipse\eclipse.exe

as above. Now the error is different:

  An error has occurred. See the log file
  e:\eclipse%203.0.0\eclipse\configuration\1094053334197.log
               [ OK ]

So, yes, eclipse is trying to resolve the % as a hexcode. But in the examples
above %M is never going to be a hexcode... since M is not in the 0-9A-F char range.
