Build ID: M20071023-1652 Steps To Reproduce: 1. Introduce some compilation error in some code 2. Cleanup the projects 3. You get a NPE while compiling the code, in a place which has nothing to do with the bad code. More information: Here is the stack trace I get : Severity and Description Path Resource Location Creation Time Id Internal compiler error java.lang.NullPointerException at org.eclipse.jdt.internal.compiler.lookup.ReferenceBinding.binarySearch(ReferenceBinding.java:108) at org.eclipse.jdt.internal.compiler.lookup.ParameterizedTypeBinding.getMethods(ParameterizedTypeBinding.java:528) at org.eclipse.jdt.internal.compiler.lookup.Scope.findMethod(Scope.java:1063) at org.eclipse.jdt.internal.compiler.lookup.Scope.getMethod(Scope.java:2060) at org.eclipse.jdt.internal.compiler.ast.MessageSend.resolveType(MessageSend.java:417) at org.eclipse.jdt.internal.compiler.ast.ReturnStatement.resolve(ReturnStatement.java:216) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolveStatements(AbstractMethodDeclaration.java:429) at org.eclipse.jdt.internal.compiler.ast.MethodDeclaration.resolveStatements(MethodDeclaration.java:196) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolve(AbstractMethodDeclaration.java:400) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1085) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1164) at org.eclipse.jdt.internal.compiler.ast.CompilationUnitDeclaration.resolve(CompilationUnitDeclaration.java:366) at org.eclipse.jdt.internal.compiler.Compiler.process(Compiler.java:623) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:392) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile(AbstractImageBuilder.java:362) at org.eclipse.jdt.internal.core.builder.BatchImageBuilder.compile(BatchImageBuilder.java:173) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile(AbstractImageBuilder.java:299) at org.eclipse.jdt.internal.core.builder.BatchImageBuilder.build(BatchImageBuilder.java:59) at org.eclipse.jdt.internal.core.builder.JavaBuilder.buildAll(JavaBuilder.java:269) at org.eclipse.jdt.internal.core.builder.JavaBuilder.build(JavaBuilder.java:172) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:624) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:166) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:197) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:246) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:249) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:302) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:334) at org.eclipse.core.internal.resources.Workspace.build(Workspace.java:328) at org.eclipse.ui.actions.GlobalBuildAction$1.run(GlobalBuildAction.java:183) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) shared-ldap/src/main/java/org/apache/directory/shared/ldap/schema DefaultObjectClass.java line 0 1198685607498 283607 The code I modified to get this error is certainly wrong, but I should not get such an error... Here is the trace I get with Maven (which seems the origin of the syntax error I introduced) : [INFO] Compilation failure /home/elecharny/apacheds/bigbang/apacheds/core/src/main/java/org/apache/directory/server/core/schema/SchemaSubentryModifier.java:[149,19] cannot find symbol symbol : constructor AddOperationContext(org.apache.directory.shared.ldap.name.LdapDN,javax.naming.directory.Attributes,boolean) location: class org.apache.directory.server.core.interceptor.context.AddOperationContext /home/elecharny/apacheds/bigbang/apacheds/core/src/main/java/org/apache/directory/server/core/schema/SchemaSubentryModifier.java:[198,19] cannot find symbol symbol : constructor AddOperationContext(org.apache.directory.shared.ldap.name.LdapDN,javax.naming.directory.Attributes,boolean) location: class org.apache.directory.server.core.interceptor.context.AddOperationContext ... (a lot more...)
Bug was incorrectly categorized as "APT" subcomponent; changing to "Core". Looks to me like another occurrence of Bug 170896?
Indeed... I have a snapshot of my whole sources when the bug happened, but I'm afraid I doomed the workspace. Is it from any interest that I attach a 18,5 Mb of source + subversion infos? Last, not least, this error didn't occured again after I quit eclipse and launched it again. (FYI, I tested eclipse-3.4-M4 with the very same framework, and got the same NPE).
Are you using a JRockit 27.1 VM?
(In reply to comment #3) > Are you using a JRockit 27.1 VM? > 27.4.0, actually (I just switched from 27.4.3, and I get the very same problem). But I switched back to Sun 1.6_03 yesturday, because JRockit debugger seems to stale on some operations... So far, I haven't seen NPE while compiling the code with SUN JVM, so it may be a problem related to the JVM. I keep an eye on this bug to see if I can reproduce it with SUN JVM. I may test it with IBM JVM too...
Thans for the feedback. So, set so far as duplicate of bug 170896 *** This bug has been marked as a duplicate of bug 170896 ***
Verified for 3.6M7
