[eclipse-dev] [WIN32] if you were using 1126 or 1127 and want to upgrade

[celek@xxxxxxxxxx]

This not if for those who are using 1126 or 1127 on windows, and want to
upgrade to the latest integration build.

It will happen if...
- you are on Windows
- you had 1126 or 1127 installed
- you installed the latest integration build by deleteing 1126/1127 and
installing the latest in the same directory

Symptom:
The splash screen will open, and close. You will have a small dialog
telling you there is an error and asking you to open the file .log. This
file will contain something like

!MESSAGE Exception launching the Eclipse Platform:
!STACK
java.lang.NoClassDefFoundError: org/eclipse/swt/widgets/Widget
      at java.lang.Class.newInstance0(Native Method)
      at java.lang.Class.newInstance(Class.java:232)

Solution:
Delete the directory .config under .metadata of your workspace

What happened:
The WIN32 feature fragment were not installed in 1126/1127. Eclipse worked
fine because all the plugins were present and fragments were considered
'orphan plugins'.
When you installed the latest Integration build, the Fragment Features were
found and eclipse thoughts the features were new, thus disabled them in
order to ask you if you wanted to enable them. By disabling the feature,
win32 fragments were disabled, thus not found upon startup...
