IndexNotReadyException inside runReadActionInSmartMode
已回答
private @NotNull CancellablePromise<Map<String, PsiClass>> buildClassCacheAndSetClassOriginalValues(List<String> allReferencedClasses, GlobalSearchScope projectScope) {
return ReadAction.nonBlocking(() -> DumbService.getInstance(project).runReadActionInSmartMode(() -> {
final Map<String, PsiClass> classCache = new HashMap<>();
for (String referencedClass : allReferencedClasses) {
final PsiClass psiClass = classCache.computeIfAbsent(referencedClass, x -> JavaFileManager.getInstance(project).findClass(x, projectScope));
if (psiClass != null) {
psiClass.putUserData(Keys.ORIGINAL_REFERENCE_FQN, psiClass.getQualifiedName());
psiClass.putUserData(Keys.ORIGINAL_REFERENCE_VISIBILITY, VisibilityUtil.getAccessLevel(VisibilityUtil.getVisibilityModifier(psiClass.getModifierList())));
}
}
return classCache;
})).submit(AppExecutorUtil.getAppExecutorService());
}
results in the following stack trace:

at java.base/java.lang.Thread.run(Thread.java:840)I thought runReadActionInSmartMode was supposed to take care of that?
It is run like this:
DumbService.getInstance(project)
.runWhenSmart(() ->
buildClassCacheAndSetClassOriginalValues(allReferencedClasses, projectScope)…

Hi Simon,
The method doc says:
To me, it looks like the error is in wrapping the whole in the read action:
Argh, thank you for the hint, Karol.
Getting around all the slow operations and EDT and background thread etc. stuff isn't trivial. The JavaDoc already helps a lot but every time I get an error because I use a slow operation when it's not allowed or try to access the index when it's not ready yet I'm stumped again.
