Description Thomas Hallgren CLA 2014-10-07 10:51:24 EDT 
The constructor of class org.eclipse.osgi.internal.framework.EquinoxConfiguration violates the contract of java.util.Properties. Javadoc says:

"The Properties class represents a persistent set of properties ... Each key and its corresponding value in the property list is a string."

The constructor adds a NULL_CONFIG object using the inherited Hashtable.put method. This leads to problems down the line for code that assumes that a Properties instance contains String only. All Buckminster builds are now crashing to name one such problem.

The fact that the NULL_CONFIG implements the toString() method doesn't help. (although it did make finding the problem difficult. An unquoted null printout in the debugger is usually null).

This is a regression introduced when attempting to fix another regression in bug 441377. See this commit:
