Ran into a similar issue today. In my case, it was the shade plugin that was the culprit, in addition to springframework.org having an outage. The following snippet cleared things up:

myTxtbx.Text = "Enter text here...";
myTxtbx.GotFocus += GotFocus.EventHandle(RemoveText);

Custom thread pool in Java 8 parallel stream
...s://bugs.openjdk.java.net/browse/JDK-8190974.
Example of the latter on my machine which has 8 processors. If I run the following program:

Apply pandas function to column to create multiple new columns?
