Hi Alexei,

You can  select tests.api.org.punit.all.AllTests, and select Run As -> JUnit
test to run all tests by JUnit, or  select
tests.api.org.punit.all.PUnitAllTests and select Run As -> Java Application
to run all tests by p-unit.

It's a "bug"... the problem of method signature. :)

6. Also I see that tests.api.org.punit.testclasses.LoopTestClass was

SoloRunnerTest#testRunLoopTest and ConcurrentRunnerTest#testRunLoopTest test
the  LoopTestClass. LoopTestSample in punit.samples shows how to run a Loop
test.

When I ran both problematic classes as standalone applications I could

It's because of my poor documentation. Sorry! Thanks!
