ClassCastException from RawCaptures.getCaptures

[zulus]

Looks like tm4e have trouble with parsing own built-in language_pack. There is a ClassCastException in logs, that prevents syntax coloring for vue files.

Problem appear during initial loading (startup) org.eclipse.tm4e.language_pack/syntaxes/go/go.tmLanguage.json, and loading patterns for keyword.function.go

I had to modify RawCaptures a little bit to catch stacktrace:

java.lang.ClassCastException: class org.eclipse.tm4e.core.internal.parser.PropertySettable$ArrayList cannot be cast to class org.eclipse.tm4e.core.internal.grammar.raw.IRawRule (org.eclipse.tm4e.core.internal.parser.PropertySettable$ArrayList and org.eclipse.tm4e.core.internal.grammar.raw.IRawRule are in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @759cdfc8)

I cannot reproduce this. Please provide a reproducible example and a stacktrace.

It depends to disk load order, once I'll find correct scenario I'll put here. ClassCastException normally is hidden
