This problem does not occur if there is source code attached for the target method.

1. Write some code that calls a method in Java that you don't have source for. For example: private void foo() { String.format("%s", "bar"); }

2. Click on the method name, "format", and press F3 to open the declaration.

Assuming you don't have the source for String.class you should see "An error has occurred. See error log for more details. java.lang.NullPointerException".

The error log has this stack trace:
