I noticed a serious problem in Eclipse F2 but I didn't figure out yet, how to 
reproduce this. I will try next days with a new workspace but couldn't because 
of anoter bug 18677.

Environment config:

- imported plugin project A (from "com.ibm.etools.draw2")
required plugins: org.eclipse.swt + org.eclipse.ui
reexports: ECLIPSE_HOME/plugins/org.eclipse.swt/win32_2.0.0/ws/win32/swt.jar

- created plugin project B
required plugins: org.apache.xerces

-created plugin project C
requires plugins: none

- created plugin project D
required plugins: org.eclipse.core.runtime, org.eclipse.core.resources, 
org.eclipse.ui, org.eclipse.jdt.core, org.eclipse.jdt.ui, 
org.eclipse.launching, org.apache.xerces, B, C

- created plugin project E
required plugins: org.eclipse.core.resources, org.eclipse.ui, 
com.ibm.etools.gef, com.ibm.etools.draw2d, B, C, D

- created JAVA project F
project dependencies: A, D, E
library dependencies: ECLIPSE_HOME/plugins/org.eclipse.ui_2.0.0/workbench.jar

Now while editing classes of JAVA project F, various problems occours that IMHO 
should have the same cause. 

These problems are:

1.
Code Assist could not find _ANY_ classes except the current one I'm editing. 
Even classes of the same project could not be found. (Navigate->Open Type shows 
up all available classes). 
Code Completion for members and vars of already imported classes work but not 
for class names. 
Code Completion also doesn't work for constructors. If I type a class and try 
to invoke Code Assist to find available constructors, Message "No Completions 
found" appears in status bar.

2.
If I remove library workbench.jar from project F library dependencies, class 
names are found, but Code Assist shows incorrect member information for one 
class of project E. Some members are missing. Code Assists also doesn't work on 
constructors for some classes of project D.

3. If I remove project E from project dependencies, everything works even. Even 
if I readd workbench.jar. Code Assist finds all classes, members and so on.

It's very difficult to reproduce this problem on other installations. If I find 
a way, I will post it ASAP. Maybe someone can have a look over affected code, 
to confirm there is no loop or anything else in building classpaths for Code 
Assist or compiler.
