У меня случайно возникает эта проблема, когда я пытаюсь инициализировать ehcache:
Caused by: org.jboss.weld.exceptions.WeldException: WELD-000049 Unable to invoke [method] @PostConstruct private cerebro84.util.cache.CacheManagerServiceBean.initialize() on cerebro84.util.cache.CacheManagerServiceBean@3ee90439

Странное поведение в том, что если я перезапустил контейнер (weblogic), он работает нормально. Это класс, который я использую для инициализации кэша, обрезая до самого необходимого:
import javax.annotation.PostConstruct;
import javax.cache.CacheManager;
import javax.cache.Caching;
import javax.enterprise.context.ApplicationScoped;
import lombok.Getter;
import lombok.extern.slf4j.Slf4j;
@Slf4j
@ApplicationScoped
public class CacheManagerServiceBean {
private static final String EHCACHE_CONFIG_FILE_PATH = "/ehcache.xml";
@Getter
private CacheManager cacheManager = null;
@Getter
private boolean cacheEnabled = false;
@PostConstruct
private void initialize() {
logger.info("Instantiating cache manager");
try {
this.cacheManager = Caching.getCachingProvider().getCacheManager(
getClass().getResource(EHCACHE_CONFIG_FILE_PATH).toURI(),
getClass().getClassLoader());
cacheEnabled = true;
} catch (Exception|NoClassDefFoundError e) {
logger.error("Unable to enable cache", e);
}
}
}
Я попытался добавить следующую строку
<wls:package-name>net.sf.saxon.*</wls:package-name>
до /META-INF/weblogic-application.xml, но это не помогло. Саксонская является прямой зависимостью модуля:
<dependency>
<groupId>net.sf.saxon</groupId>
<artifactId>Saxon-HE</artifactId>
<version>9.5.1-8</version>
</dependency>
Модуль упакован как jar в многомодульном приложении ear.
Кто-нибудь знает, как убедиться, что класс XPathException всегда найден саксонским? Заранее спасибо.
