Description

In order for mutable numbers to be used in editable JTable models, they need to have a constructor accepting a string. The following stack trace was the result of double-clicking on a table cell displaying a MutableDouble instance:

java.lang.NoSuchMethodException: org.apache.commons.lang.mutable.MutableDouble.<init>(java.lang.String)

The editor had been installed in this way:

JTable table = ...;
table.setDefaultEditor(Number.class, table.getDefaultEditor(Double.class));
