* If a loop with an excessive amount of clauses is created, so that the number of parameters to the resulting loop
* handle exceeds the allowed maximum, an IAE must be signalled. The test is run first in LambdaForm interpretation mode
* and then in default mode, wherein bytecode generation falls back to LFI mode due to excessively long methods.
* <p>
* By default, the test run only checks whether loop handle construction succeeds and fails. If executing the generated
* loops is desired, this should be indicated by setting the {@code java.lang.invoke.LoopCombinatorLongSignatureTest.RUN}
* environment variable to {@code true}. This is disabled by default as it considerably increases the time needed to run
* the test.
