AbstractFileLookup.lookupFileStrict does not use specified classloader ---------------------------------------------------------------------- Key: ISPN-5949 URL: https://issues.jboss.org/browse/ISPN-5949 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 8.0.1.Final, 7.2.5.Final, 8.1.0.Beta1 Reporter: Stéphane Nicoll Assignee: Sebastian Łaskawiec Fix For: 9.0.0.Alpha4, 9.0.0.Final I am reporting this issue on behalf of a Spring Boot user that created [an issue in our tracker|https://github.com/spring-projects/spring-boot/issues/4418]. Spring Boot creates a JCache manager using the standard API, passing a {{Classloader}} to it. It's unclear at this point if we pass the proper classloader or not but it doesn't matter that much at this point since the classloader argument is being ignored by {{AbstractFileLookup.lookupFileStrict}}. {noformat} Caused by: java.lang.IllegalArgumentException: URI is not hierarchical at java.io.File.<init>(File.java:418) at org.infinispan.commons.util.AbstractFileLookup.lookupFileStrict(AbstractFileLookup.java:63) at org.infinispan.jcache.embedded.JCacheManager.getConfigurationBuilderHolder(JCacheManager.java:98) at org.infinispan.jcache.embedded.JCacheManager.<init>(JCacheManager.java:56) at org.infinispan.jcache.embedded.JCachingProvider.createCacheManager(JCachingProvider.java:46) at org.infinispan.jcache.AbstractJCachingProvider.getCacheManager(AbstractJCachingProvider.java:66) at org.springframework.boot.autoconfigure.cache.JCacheCacheConfiguration.createCacheManager(JCacheCacheConfiguration.java:97) at org.springframework.boot.autoconfigure.cache.JCacheCacheConfiguration.jCacheCacheManager(JCacheCacheConfiguration.java:80) {noformat} When not running as a fat jar (i.e. running the main class in the IDE), the code works as expected (as the classloader does not matter in this case).
