Code model cache was reworked in Netbeans 8.0.
Comment 4 Alexander Simon 2015-11-11 09:20:19 UTC 
see steps to reproduce in the exception report 800811
Comment 5 Vladimir Voskresensky 2015-11-11 14:18:22 UTC 
Thanks for reproducible test case.
Comment 6 Vladimir Voskresensky 2015-11-11 14:48:46 UTC 
To reproduce the issue close Navigator and use the following c++11 code:
namespace NS {
inline namespace {
void foo() {
  return boo1;
}
}
}


put cursor on foo, wait mark occurrences.
move caret after boo1|

set breakpoint in NamespaceDefinitionImpl.getScopeElements at 
"if (isOfMyScope(decl)) {"
set breakpoint in ProjectBase.setDisposed at "disposing.set(true);"
remove symbol "1", wait 1st breakpoint hit when decl is FunctionDDImpl for "foo"
invoke CA->Reparse project wait 2nd hit

step into 1st till NamespaceImpl.isNamespaceScope before "func.getContainingFile()"
check that func.isValid returns true

do one step for 2nd breakpoint and check that on the 1st now
func.isValid returns false.
Now set break in FileImpl constructor and resume 2nd till FileImpl constructor is hit

try step over in 1st and get NPE.

The reason is:
- getContainingFile in Offsetable base use fileRef (initialized in onDispose) and when null, then calls "file = UIDCsmConverter.UIDtoFile(fileUID);"
but repository is cleaned when Reparse is invoked and no FileImpl can be returned by fileUID
- onDispose was not invoked, because we don't deserialize all model when user invoke Reparse.

Log: fixed #226012 - [74cat] AssertionError: no object for UID KeyBasedUID on FileKey
- always use reference to FileImpl, because it holds reference to "disposed" AtomicBoolean from Project. This is the only way to know that project was requested for Reparse and all live objects became invalid. We want to protect slow clients from returning null from getContainingFile, so hold file
