JSR223: make clear two different implementations of RuleRegistry are injected

[dilyanpalauzov]

For some reason JSR223 injects two different implementations of the org.openhab.core.automation interface.

This is confirmed by the Groovy code below:

import org.openhab.core.automation.RuleRegistry

org.slf4j.Logger logger = org.slf4j.LoggerFactory.getLogger("a1")

scriptExtension.importPreset("RuleSupport")
logger.info(rules.class.toString())
logger.info(rules instanceof RuleRegistry? "true": "false") // from Default preset
logger.info(rules instanceof org.openhab.core.automation.Action ? "true" : "false")

logger.info(ruleRegistry.class.toString())
logger.info(ruleRegistry instanceof RuleRegistry ? "true" : "false") // from RuleSupport preset
logger.info(ruleRegistry instanceof org.openhab.core.automation.Action ? "true" : "false")

which prints

2024-09-04 14:11:12.512 [INFO ] [ort.loader.AbstractScriptFileWatcher] - (Re-)Loading script '/etc/openhab/automation/jsr223/t.groovy'

2024-09-04 14:11:12.563 [INFO ] [a1 ] - false

I asked for the rationale on this at https://community.openhab.org/t/why-does-jsr223-provide-two-implementations-of-the-ruleregistry-interface/.
