Visual Studio Code's Java Compiler Not Showing Certain Errors

[key6oardWarrior]

When running Java code I have noticed that some compile time errors will not be displayed. For example, the following code should throw an error, "HashMap<Integer, Integer> hashMapName = new HashMap<Integer, String>();" Instead of seeing, "Unresolved compilation problems:
Type mismatch: cannot convert from HashMap<Integer,Integer> to HashMap<Integer,String>
The method put(Integer, String) in the type HashMap<Integer,String> is not applicable for the arguments (int, int)" The compiler displays, "Exception in thread "main" java.lang.Error: Unresolved compilation problem:

    at Test.main(Test.java:8)" If I want to see the error message then I have to read the class file in order to determin what the error is and where it is located. I was able to reproduce the bug in a small and simple Java file. I noticed that the bug shows up when I declare the like, "HashMap<dataTypeA, dataTypeB> name = new HashMap<dataTypeC, dataTypeD>" Where dataType A - D could be any data type I want it to be. The bug only occors when dataTypeC is different from dataTypeA and or dataTypeD is differnt from dataTypeB.
