我不是处理这些东西（修复IDE）的专家，但我得到了116个这样的异常：
相等对象必须具有相等的哈希码。在重新散列期间，特罗夫 发现以下两个对象声称相等（如 java.lang.Object.equals（） 或 TObjectHashingStrategy.equals（）） 但是 他们的哈希码（或由您的TObjectHashingStrategy计算的哈希码） 不相等。这违反了 java.lang.Object.hashCode（）. 请参阅该方法中的项目符号 文档。object #1 =PsiArrayAccessExpression：args[0] （class com.intellij.psi.impl.source.tree.java.PsiArrayAccessExpressionImpl）， 哈希代码=1492582784;object #2 =PsiArrayAccessExpression：args[0] （类 com.intellij.psi.impl.source.tree.java.PsiArrayAccessExpressionImpl）， hashCode=1492582784：相等的对象必须具有相等的哈希码。在 重新梳理，Trove发现以下两个对象声称是 equal（如 java.lang.Object.equals（） 或 TObjectHashingStrategy.equals（）），但他们的哈希码（或那些 由您的TObjectHashingStrategy计算）不相等。这违反了 java.lang.Object.hashCode（） 的一般合约。 请参阅项目符号 该方法文档中的两个。对象 #1 =PsiArrayAccessExpression：args[0] （class com.intellij.psi.impl.source.tree.java.PsiArrayAccessExpressionImpl）， 哈希代码=1492582784;object #2 =PsiArrayAccessExpression：args[0] （类 com.intellij.psi.impl.source.tree.java.PsiArrayAccessExpressionImpl）， 哈希代码=1492582784
即使在重新启动IDE后，它仍然给我带来问题。它不会自动建议或填充变量/函数等。我必须从字面上制作我的应用程序，只是通过记住事情，我该如何解决这个问题？这很烦人。
我注意到每次按 Ctrl+空格键（用于自动建议）时都会抛出它。
帮助？

对于那些多年后仍然无法找到解决方案的人来说，我遇到了同样的问题并最终解决了它。如果您与我的案例类似，请参阅下文。
我的问题是使用JSONObject和JSONArray对象。基本上，我会阅读，例如，一个JSONObject，并尝试在第一个中获取另一个JSONObject，就像这样。
假设您正在阅读此消息：
{
"sub1": ["array element 1", "array element 2", "array element 3"],
"sub2": {
"name": "name for sub-object sub2",
"value": "value for sub-object sub2 or whatever"
}
}
假设整个对象是在 args[0] 中提供给我的，那么我正在阅读它所做的是这样的：
JSONObject globalObject = (JSONObject) args[0];
JSONArray sub1= (JSONArray) globalObject.get("sub1");//<-- the problem
JSONObject sub2 = (JSONObject) globalObject.get("sub2");//<-- also the problem
String arrayElement1 = sub1.get(0);
String nameSub2 = sub2.getString("name");
溶液问题来自将内容从JSONObject/JSONArray的get()方法转换为JSONObject/JSONArray。没有必要这样做，因为您只需执行getJSONObject(/*value*/)或getJSONObject(/*value*/)，并获得已经属于 JSONObject 或JSONArray 类型的结果
所以我上面的代码应该看起来像这样：
JSONObject globalObject = (JSONObject) args[0];//<--only this needs to be casted
JSONArray sub1= globalObject.getJSONArray("sub1");//<-- got rid of the castnig
JSONObject sub2 = globalObject.getJSONObject("sub2");//<-- no more casting
String arrayElement1 = sub1.get(0);
String nameSub2 = sub2.getString("name");
希望这对某人有所帮助。
