ClassFinder logs lots of warnings when the maven repository path contains "infinispan" -------------------------------------------------------------------------------------- Key: ISPN-8183 URL: https://issues.jboss.org/browse/ISPN-8183 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.1.0.Final Reporter: Dan Berindei Assignee: Dan Berindei Fix For: 9.0.4.Final, 9.1.1.Final, 8.1.10.Final, 8.2.9.Final {{ClassFinder.infinispanClasses()}} tries to find all Infinispan classes by iterating through the classpath entries and adding classes from each entry that contains {{infinispan}} in the path or has a sub-sub-...directory called {{infinispan}}. This doesn't work if the Maven repository path contains {{infinispan}}, as it happens on the CI agents, and all the classpath entries are included. When trying to parse a class that doesn't start with {{org.}}, {{ClassFinder}} then throws this exception: {noformat} 08:15:47,413 WARN (TestNG:[]) [ClassFinder] From jar path com/github/benmanes/caffeine/base/UnsafeAccess.class could not load class null java.lang.StringIndexOutOfBoundsException: String index out of range: -1 at java.lang.String.substring(String.java:1960) ~[?:1.8.0_141] at org.infinispan.commons.util.ClassFinder.toClassName(ClassFinder.java:183) ~[infinispan-commons.jar:9.1.1-SNAPSHOT] at org.infinispan.commons.util.ClassFinder.findClassesOnPath(ClassFinder.java:144) [infinispan-commons.jar:9.1.1-SNAPSHOT] at org.infinispan.commons.util.ClassFinder.infinispanClasses(ClassFinder.java:90) [infinispan-commons.jar:9.1.1-SNAPSHOT] at org.infinispan.commons.util.ClassFinder.infinispanClasses(ClassFinder.java:72) [infinispan-commons.jar:9.1.1-SNAPSHOT] at org.infinispan.util.ClassFinderTest.testInfinispanClassesNonEmpty(ClassFinderTest.java:11) [test-classes/:?] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_141] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[?:1.8.0_141] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:1.8.0_141] at java.lang.reflect.Method.invoke(Method.java:498) ~[?:1.8.0_141] at org.testng.internal.MethodInvocationHelper.invokeMethod(MethodInvocationHelper.java:84) [testng-6.8.8.jar:?] at org.testng.internal.Invoker.invokeMethod(Invoker.java:714) [testng-6.8.8.jar:?] at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:901) [testng-6.8.8.jar:?] at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1231) [testng-6.8.8.jar:?] at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:127) [testng-6.8.8.jar:?] at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:111) [testng-6.8.8.jar:?] at org.testng.TestRunner.privateRun(TestRunner.java:767) [testng-6.8.8.jar:?] at org.testng.TestRunner.run(TestRunner.java:617) [testng-6.8.8.jar:?] at org.testng.SuiteRunner.runTest(SuiteRunner.java:348) [testng-6.8.8.jar:?] at org.testng.SuiteRunner.access$000(SuiteRunner.java:38) [testng-6.8.8.jar:?] at org.testng.SuiteRunner$SuiteWorker.run(SuiteRunner.java:382) [testng-6.8.8.jar:?] at org.testng.internal.thread.ThreadUtil$2.call(ThreadUtil.java:64) [testng-6.8.8.jar:?] at java.util.concurrent.FutureTask.run(FutureTask.java:266) [?:1.8.0_141] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) [?:1.8.0_141] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) [?:1.8.0_141] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_141] {noformat}
