Calling CelRuntimeBuilder.setStandardEnvironmentEnabled(false) does not disable standard functions

[modhanami]

Note

I see StandardFunctions.add() being called twice in CelRuntimeLegacyImpl.build(), once in DefaultDispatcher.create() unconditionally, and another when standardEnvironmentEnabled is true.

Are these intended? Or how can I disable the standard functions completely to achieve something like cel-go's NewCustomEnv?

cel-java/runtime/src/main/java/dev/cel/runtime/CelRuntimeLegacyImpl.java

Lines 230 to 233 in 4f8f455

	DefaultDispatcher dispatcher = DefaultDispatcher.create(options, dynamicProto);
	if (standardEnvironmentEnabled) {
	StandardFunctions.add(dispatcher, dynamicProto, options);
	}

cel-java/runtime/src/main/java/dev/cel/runtime/DefaultDispatcher.java

Lines 76 to 80 in 4f8f455

	public static DefaultDispatcher create(CelOptions celOptions, DynamicProto dynamicProto) {
	DefaultDispatcher dispatcher = new DefaultDispatcher(celOptions);
	StandardFunctions.add(dispatcher, dynamicProto, celOptions);
	return dispatcher;
	}

This is most definitely unintended. #256 should fix this when it lands.

Thanks for reporting.
