AbstractBeanInfoFactory throws StringIndexOutOfBoundsException for short method names ------------------------------------------------------------------------------------- Key: JBMICROCONT-229 URL: http://jira.jboss.com/jira/browse/JBMICROCONT-229 Project: JBoss MicroContainer Issue Type: Bug Components: Container Affects Versions: JBossMC-2.0.0.Beta7 Reporter: Brian Stansberry Assigned To: Adrian Brock Fix For: JBossMC-2.0.0.CR1 Creating a bean of a type that contains a method whose name is 2 chars or less results in the following: java.lang.StringIndexOutOfBoundsException: String index out of range: -1 at java.lang.String.substring(String.java:1768) at java.lang.String.substring(String.java:1735) at org.jboss.beans.info.plugins.AbstractBeanInfoFactory.getUpperPropertyName(AbstractBeanInfoFactory.java:93) at org.jboss.beans.info.plugins.AbstractBeanInfoFactory.getBeanProperties(AbstractBeanInfoFactory.java:234) at org.jboss.beans.info.plugins.AbstractBeanInfoFactory.getBeanInfo(AbstractBeanInfoFactory.java:141) at org.jboss.config.plugins.AbstractConfiguration.getBeanInfo(AbstractConfiguration.java:71) at org.jboss.kernel.plugins.config.AbstractKernelConfig.getBeanInfo(AbstractKernelConfig.java:55) at org.jboss.kernel.plugins.config.AbstractKernelConfigurator.getBeanInfo(AbstractKernelConfigurator.java:65) at org.jboss.kernel.plugins.config.AbstractKernelConfigurator.getBeanInfo(AbstractKernelConfigurator.java:84) at org.jboss.kernel.plugins.dependency.PreInstallAction.installActionInternal(PreInstallAction.java:62) at org.jboss.kernel.plugins.dependency.KernelControllerContextAction.installAction(KernelControllerContextAction.java:135) at org.jboss.kernel.plugins.dependency.KernelControllerContextAction.installAction(KernelControllerContextAction.java:46) at org.jboss.dependency.plugins.action.SimpleControllerContextAction.simpleInstallAction(SimpleControllerContextAction.java:62) at org.jboss.dependency.plugins.action.AccessControllerContextAction.install(AccessControllerContextAction.java:71) at org.jboss.dependency.plugins.AbstractControllerContextActions.install(AbstractControllerContextActions.java:51) at org.jboss.dependency.plugins.AbstractControllerContext.install(AbstractControllerContext.java:327) at org.jboss.dependency.plugins.AbstractController.install(AbstractController.java:1309) at org.jboss.dependency.plugins.AbstractController.incrementState(AbstractController.java:734) at org.jboss.dependency.plugins.AbstractController.resolveContexts(AbstractController.java:862) at org.jboss.dependency.plugins.AbstractController.resolveContexts(AbstractController.java:784) at org.jboss.dependency.plugins.AbstractController.install(AbstractController.java:574) at org.jboss.dependency.plugins.AbstractController.install(AbstractController.java:398) at org.jboss.deployers.vfs.deployer.kernel.BeanMetaDataDeployer.deploy(BeanMetaDataDeployer.java:69) ... This is from attempt to create an instance of org.jgroups.JChannel, which includes a method named up(). Problem is in AbstractBeanInfoFactory: protected static String getUpperPropertyName(String name) { int start = 3; if (name.startsWith("is")) start = 2; return name.substring(start); } A simple fix is to make the first line int start = Math.min(3, name.length); which will result in a return value of "" from name.substring(start) if name is 3 chars or less. Alternatively, change getBeanProperties() to not call getUpperPropertyName() until it has already determined the method is a getter or a setter.
