[ https://issues.jboss.org/browse/JBIDE-17877?page=com.atlassian.jira.plugi... ] Denis Golovin updated JBIDE-17877: ---------------------------------- Description: Exception below was fixed by checking instance of target obect before casting to IType see JBIDE-17716 and skipping the rest of the code. Do we need to do something extra in this case? {code} org.jboss.tools.common Error Mon Jun 30 12:28:44 CEST 2014 org.eclipse.jdt.internal.core.TypeParameter cannot be cast to org.eclipse.jdt.core.IType org.jboss.tools.common.validation.JBTValidationException: org.eclipse.jdt.internal.core.TypeParameter cannot be cast to org.eclipse.jdt.core.IType at org.jboss.tools.common.validation.AsYouTypeValidatorManager.validate(AsYouTypeValidatorManager.java:187) at org.jboss.tools.common.validation.AsYouTypeValidatorManager.validateString(AsYouTypeValidatorManager.java:205) at org.jboss.tools.common.validation.AsYouTypeValidatorManager.validateString(AsYouTypeValidatorManager.java:200) at org.jboss.tools.common.validation.java.JavaDirtyRegionProcessor.endProcessing(JavaDirtyRegionProcessor.java:498) at org.eclipse.wst.sse.ui.internal.reconcile.DirtyRegionProcessor$BackgroundThread.run(DirtyRegionProcessor.java:697) Caused by: java.lang.ClassCastException: org.eclipse.jdt.internal.core.TypeParameter cannot be cast to org.eclipse.jdt.core.IType at org.jboss.tools.ws.jaxrs.core.jdt.SourceType.from(SourceType.java:79) at org.jboss.tools.ws.jaxrs.core.jdt.JdtUtils.getReturnType(JdtUtils.java:1143) at org.jboss.tools.ws.jaxrs.core.jdt.JdtUtils.resolveMethodSignature(JdtUtils.java:1067) at org.jboss.tools.ws.jaxrs.core.jdt.JdtUtils.resolveMethodSignatures(JdtUtils.java:1037) at org.jboss.tools.ws.jaxrs.core.jdt.CompilationUnitsRepository.recordAST(CompilationUnitsRepository.java:112) at org.jboss.tools.ws.jaxrs.core.jdt.CompilationUnitsRepository.getAST(CompilationUnitsRepository.java:76) at org.jboss.tools.ws.jaxrs.ui.internal.validation.JaxrsMetamodelValidator.validate(JaxrsMetamodelValidator.java:413) at org.jboss.tools.common.validation.AsYouTypeValidatorManager.validate(AsYouTypeValidatorManager.java:183) ... 4 more {code} was: {code} org.jboss.tools.common Error Mon Jun 30 12:28:44 CEST 2014 org.eclipse.jdt.internal.core.TypeParameter cannot be cast to org.eclipse.jdt.core.IType org.jboss.tools.common.validation.JBTValidationException: org.eclipse.jdt.internal.core.TypeParameter cannot be cast to org.eclipse.jdt.core.IType at org.jboss.tools.common.validation.AsYouTypeValidatorManager.validate(AsYouTypeValidatorManager.java:187) at org.jboss.tools.common.validation.AsYouTypeValidatorManager.validateString(AsYouTypeValidatorManager.java:205) at org.jboss.tools.common.validation.AsYouTypeValidatorManager.validateString(AsYouTypeValidatorManager.java:200) at org.jboss.tools.common.validation.java.JavaDirtyRegionProcessor.endProcessing(JavaDirtyRegionProcessor.java:498) at org.eclipse.wst.sse.ui.internal.reconcile.DirtyRegionProcessor$BackgroundThread.run(DirtyRegionProcessor.java:697) Caused by: java.lang.ClassCastException: org.eclipse.jdt.internal.core.TypeParameter cannot be cast to org.eclipse.jdt.core.IType at org.jboss.tools.ws.jaxrs.core.jdt.SourceType.from(SourceType.java:79) at org.jboss.tools.ws.jaxrs.core.jdt.JdtUtils.getReturnType(JdtUtils.java:1143) at org.jboss.tools.ws.jaxrs.core.jdt.JdtUtils.resolveMethodSignature(JdtUtils.java:1067) at org.jboss.tools.ws.jaxrs.core.jdt.JdtUtils.resolveMethodSignatures(JdtUtils.java:1037) at org.jboss.tools.ws.jaxrs.core.jdt.CompilationUnitsRepository.recordAST(CompilationUnitsRepository.java:112) at org.jboss.tools.ws.jaxrs.core.jdt.CompilationUnitsRepository.getAST(CompilationUnitsRepository.java:76) at org.jboss.tools.ws.jaxrs.ui.internal.validation.JaxrsMetamodelValidator.validate(JaxrsMetamodelValidator.java:413) at org.jboss.tools.common.validation.AsYouTypeValidatorManager.validate(AsYouTypeValidatorManager.java:183) ... 4 more {code} follow the steps form JBIDE-17716 and add class below to replicate the issue -- This message was sent by Atlassian JIRA (v6.2.6#6264)
