Update KotlinLateinitFilter for Kotlin 1.5

[Godin]

Currently execution of

mvn clean package -Dkotlin.version=1.5.0-M1

leads to

Failed tests:
  execute_assertions_in_comments(org.jacoco.core.test.validation.kotlin.KotlinLateinitTest): Instructions (KotlinLateinitTarget.kt:26) expected:<[FUL]LY_COVERED> but was:<[PART]LY_COVERED>

What seems to be related to the following change in Kotlin compiler - JetBrains/kotlin@7c95781

m.visitInsn(Opcodes.ACONST_NULL);
m.visitInsn(Opcodes.ATHROW);

Oh shit, I hope for Kotlin the JVM will never tighten its verifier 😱

[Godin]

@marchof what do you mean? according to https://docs.oracle.com/javase/specs/jvms/se16/html/jvms-6.html#jvms-6.5.athrow

If objectref is null, athrow throws a NullPointerException instead of objectref.

[marchof]

Sure... I mean something like SonarQube for bytecode 😅

ACONST_NULL
ATHROW
^ Warning: This will always result in a NPE
