Re: [protobuf] The generated java code crashes if I try to integrate it into an Eclipse Rich Client application
The generated code contains a big string literal which contains metadata about the types. The metadata is itself a protocol buffer, and is decoded at startup. It looks like it is somehow being corrupted in your environment. I don't know how that would happen. I recently wrote an Eclipse plugin that used protocol buffers and did not see any problems. That said, you can try adding this to your .proto file: option optimize_for = LITE_RUNTIME; This turns off a number of features, including self-description. Thus, the generated code will no longer contain an embedded descriptor at all.

[protobuf] The generated java code crashes if I try to integrate it into an Eclipse Rich Client application
Hi, I have problems integrating Java GPB generated code into an Eclipse Rich Client Platform Application. The same code works fine in a standalone java project but it crashes in the RCP environment at the first 'usage' of an enum value defined in GPB code: Exception in thread "Thread-3" java.lang.ExceptionInInitializerError at com.google.protobuf.DescriptorProtos $FileDescriptorProto.(DescriptorProtos.java:1687) at com.google.protobuf.Descriptors $FileDescriptor.internalBuildGeneratedFileFrom(Descriptors.java:338) at NGCMOSMsg.NGCMOSMessages.(NGCMOSMessages.java:11255) at NGCMOSMsg.NGCMOSMessages$MOSEndpoints.(NGCMOSMessages.java: 353) at communication.PostOffice.(PostOffice.java:31) at communication.PostOffice.getPostOffice(PostOffice.java:106) at ca.mda.moscs.common.Utilities$1.run(Utilities.java:130) Caused by: java.lang.IllegalArgumentException: Failed to parse protocol buffer descriptor for generated code. at com.google.protobuf.Descriptors $FileDescriptor.internalBuildGeneratedFileFrom(Descriptors.java:341) at com.google.protobuf.DescriptorProtos.(DescriptorProtos.java: 12656) ... 7 more Caused by: com.google.protobuf.InvalidProtocolBufferException: Protocol message tag had invalid wire type. at com.google.protobuf.InvalidProtocolBufferException.invalidWireType(InvalidProtocolBufferException.java: 86) at com.google.protobuf.UnknownFieldSet $Builder.mergeFieldFrom(UnknownFieldSet.java:600) at com.google.protobuf.GeneratedMessage $Builder.parseUnknownField(GeneratedMessage.java:320) at com.google.protobuf.DescriptorProtos$DescriptorProto $Builder.mergeFrom(DescriptorProtos.java:2742) at com.google.protobuf.DescriptorProtos$DescriptorProto $Builder.mergeFrom(DescriptorProtos.java:1) at com.google.protobuf.CodedInputStream.readMessage(CodedInputStream.java: 285) at com.google.protobuf.DescriptorProtos$FileDescriptorProto $Builder.mergeFrom(DescriptorProtos.java:1143) at com.google.protobuf.DescriptorProtos$FileDescriptorProto $Builder.mergeFrom(DescriptorProtos.java:1) at com.google.protobuf.AbstractMessage $Builder.mergeFrom(AbstractMessage.java:288) at com.google.protobuf.AbstractMessage $Builder.mergeFrom(AbstractMessage.java:1) at com.google.protobuf.AbstractMessageLite $Builder.mergeFrom(AbstractMessageLite.java:184) at com.google.protobuf.AbstractMessage $Builder.mergeFrom(AbstractMessage.java:792) at com.google.protobuf.AbstractMessage $Builder.mergeFrom(AbstractMessage.java:1) at com.google.protobuf.AbstractMessageLite $Builder.mergeFrom(AbstractMessageLite.java:174) at com.google.protobuf.AbstractMessage $Builder.mergeFrom(AbstractMessage.java:785) at com.google.protobuf.DescriptorProtos $FileDescriptorProto.parseFrom(DescriptorProtos.java:820) at com.google.protobuf.Descriptors $FileDescriptor.internalBuildGeneratedFileFrom(Descriptors.java:338) ... 8 more java.lang.NullPointerException at com.instantiations.designer.core.xml.model.description.ComponentPresentationHelper $ComponentPresentationCache.getCacheFile(ComponentPresentationHelper.java: 428) at com.instantiations.designer.core.xml.model.description.ComponentPresentationHelper $ComponentPresentationCache.(ComponentPresentationHelper.java: 322) at com.instantiations.designer.core.xml.model.description.ComponentPresentationHelper.getCache(ComponentPresentationHelper.java: 299) at com.instantiations.designer.core.xml.model.description.ComponentPresentationHelper.access $0(ComponentPresentationHelper.java:295) at com.instantiations.designer.core.xml.model.description.ComponentPresentationHelper $1.run(ComponentPresentationHelper.java:504) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) java.lang.NullPointerException at com.instantiations.designer.core.xml.model.description.ComponentPresentationHelper $ComponentPresentationCache.getCacheFile(ComponentPresentationHelper.java: 428) at com.instantiations.designer.core.xml.model.description.ComponentPresentationHelper $ComponentPresentationCache.(ComponentPresentationHelper.java: 322) at com.instantiations.designer.core.xml.model.description.ComponentPresentationHelper.getCache(ComponentPresentationHelper.java: 299) at com.instantiations.designer.core.xml.model.description.ComponentPresentationHelper.access $0(ComponentPresentationHelper.java:295) at com.instantiations.designer.core.xml.model.description.ComponentPresentationHelper $1.run(ComponentPresentationHelper.java:504) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) Can anybody give me a hint to address this issue?
