> AFAIK, "ThreadLocal" in Java is there to hold objects which are intented to be used  thread-wide. So, its port-equivalent "LocalDataStoreSlot" should contain objects related with the executing thread. But, since they are not declared as "static" in Analyzer.cs, FieldsReader.cs, SegmentReader.cs and TermInfosReader.cs, they are created with every class contruction, changing the behaviour of "ThreadLocal" and possibly resulting in performance degradation.
> I will attach a test case for this issue.
> If I am wrong, then there is no problem. But If I am right we are in trouble;  Since adding "static" to variables declared as LocalDataStoreSlot results in failing of almost all test cases.
