Learnings From Debugging the Undebuggable

TLDR: Do NOT Compile Java on the Fly

Nico Rehwaldt

---

Context

• Migrated Travis CI ➡️ GitHub actions
• bpmn-moddle test suite times out (ref)
• Random fail? ➡️ NO

---

What is Going on?

bpmn-moddle uses xsd-schema-validator

xsd-schema-validator uses Java for actual validation

Java is being compiled on the fly...

---

So...

{
  "name": "xsd-schema-validator",
  "scripts": {
    ...,
    "postinstall": "COMPILE JAVA HELPER"
  }
}
