Wie debuggen Unbehandelte Ausnahme/Segmentation Fehler in IBM Bluemix Delivery Pipeline

Question

Ich habe eine Toolchain in IBM Bluemix DevOps erstellt und es hat eine Delivery Pipeline App. In einer Phase versuche ich, SBT zu installieren und auszuführen, aber ich bin mit einem Problem konfrontiert. Leider kann ich anhand der Logs nicht herausfinden, worum es sich handelt, es wird nur angezeigt, dass eine unbehandelte Exception aufgetreten ist, ein Segmentierungsfehler und irgendeine Art von internem Stacktrace.

Wie kann ich debuggen, was im Container passiert, gehört zu diesem Job?

Hier ist das Konsolenprotokoll für den Job:

Answer 1

Basierend auf den Informationen in der Frage zur Verfügung gestellt ausgeführt habe, ist meine Empfehlung zu erhöhen ein Support-Ticket durch Bluemix.

Answer 2

Aus dem Protokoll sieht es aus wie JIT abstürzt, wenn es scala/collection/mutable/FlatHashTable.addElem (Ljava/lang/Object;) zu kompilieren versucht. Sie können versuchen, diese Methode von der JIT-Kompilierung auszuschließen und zu überprüfen, ob der Job ausgeführt wird. Verwenden Sie diese JVM-Option:

-Xjit: exclude = {scala/Sammlung/mutable/FlatHashTable.addElem}, dontInline = {scala/Sammlung/mutable/FlatHashTable.addElem *} *

Wenn dies funktioniert Das Problem liegt bei Java JIT und Sie sollten ein Ticket bei IBM anfordern.
