Bug: Java agent breaks an assertion in ShardingSphere

Beginne im Modul shardingsphere-spi bei RequiredSPIRegistryTest.java, insbesondere bei assertRegisteredServiceNotExisted in Zeile 40, und reproduziere den Fehler mit mvn test, während die Aufzeichnung aktiviert ist. Verfolge, warum der Test statt ServiceProviderNotFoundException eine NullPointerException erhält, und überprüfe anschließend, dass die Modultests mit aktivem Java agent erfolgreich durchlaufen.

Setup: see #105

Module: shardingsphere-spi

With the recording on, one test fails with an error:
