Summary	0003904: Dashboard refresh data uses Vaadin UI component without locking (also fixed by 0003903 in 3.9.19)
Description	The refreshData() method in the SpeedPanel component uses the CheckBox called activeOnly to retrieve the current value of the checkbox. The retrieval of the value from the checkbox is considered a UI update, and this method is called outside of a locked block of code.
Steps To Reproduce	Turn on JVM argument -ea (enable assertions). Log into the SymmetricDS console. Leave the screen at the Dashboard. Exceptions will begin to occur and continue.

pmarzullo 2019-04-08 20:33 developer ~0001404	The issue was changed by creating a new Boolean instance variable in the class and assigning that instance variable with the assignment of a value to the check box when it changed. See issue 3903 in version 3.9.19 also.
