Federates will throw a NoSuchMethodError when resigning from a federation if federates are joined.

For code brevity I did what nobody should ever do – I quietly extended the HLA spec. I added an extra constructor to all the standard exceptions that directly took a Throwable, rather than requiring (String,Throwable).

This is fine... most of the time. When isn’t it? Any time you have the standard interfaces on the classpath ahead of the portico jar.

In that case, the standard interfaces get loaded first (without extra constructor), and you get a MethodNotFoundError whenever Portico tries to create one.

Fixed by:

• Expanding all exception creation calls to use the standard version
• Removing the non-standard constructor from every exception I added it to

Lesson that should never have to be learnt: Learnt
