Generally looks good. It would be interesting see code-coverage results.

Are you sure the LFMultiThreadCachingTest is sufficiently testing the 
thread-safety of j.l.invoke classes? It might be that more threads need to be 
generated (== #cores), and the test repeatedly performed in a loop to increase 
the chance of stuff stomping on each other. (I see you have iterations in the 
outer loop of runTests, that might be sufficient, but you might need a tighter 
loop specific to each test in LFMultiThreadCachingTest).


A general comment, feel free to ignore. It's easy to use EnumSet to obtain a 
collection of enum values:

  Set<TestMethods> tms = EnumSet.allOf(TestMethods.class)

and filtered:

  Set<TestMethods> tms = EnumSet.complementOf(EnumSet.of(TestMethods.IDENTITY, 
TestMethods.CONSTANT))

(Quite concise with a static import.)

Change LambdaFormTestCase.runTests to accept a Collection<TestMethods> and you 
are good to go :-)

Paul.
