Build Identifier: Mac OS X 10.6.4 Everytime I try to launch in debug mode a web application project on my Tomcat 6 embedded server I (instantly) get the following error: Invalid memory access of location 0x14 rip=0x1005fad22 It happens both with GALILEO and HELIOS; I tried to switch between JRE 1.5 and 1.6 but nothing changed. Please also note that if I try to RUN the embedded Tomcat server it starts up without any problem Reproducible: Always Steps to Reproduce: 1.Configure a new Tomcat 6 Server 2.Create a new Dynamic Web Project 3.Right click on the newly created project and choose "Debug as => Debug on Server"
Larry, Can you perhaps take a look at this one. It doesn't sound like a WTP Server tools problem, it most likely something related to the JVM and Mac OS. One idea is to setup traces to see if we can pinpoint at what point in time the error occurs. Davide, Setup the following traces and let us know and what point in time in the trace the error occurs. To do so, immediately after the error occurs take a look at the trace and identify the last line written, another ideas is to mark down the time when the error occur, that might help to identify in which piece of code the error is occurring. org.eclipse.wst.server.core/extension_point=true org.eclipse.wst.server.core/resources=true org.eclipse.wst.server.core/listeners=true org.eclipse.wst.server.core/performance=false org.eclipse.wst.server.ui/performance=false org.eclipse.wst.server.ui/extension_point=true org.eclipse.wst.server.core/debug=true org.eclipse.wst.server.ui/debug=true
Everything related to Tomcat in WTP is written in Java (i.e. no native DLLs, etc), so it wouldn't be resposible for this. I would also assume the Tomcat configuration isn't attempting to using any of the "native" connectors, like tcnative-1.dll, which are not used by default. The cause would seem to be in either the MAC JVM or in the Eclipse interface to that JVM. There isn't enough information here to tell which. What is needed here is a crash dump from when this occurs. I don't enough about JVMs on the MAC to know if one is already being written somewhere, or if there are JVM arguments available to force one to be written. Unfortunately, with the amount of information so far, not much can be done.

Please ignore the question "Any suggestion about generating the crash dump file?" on my previous comment. It was due to a cut & paste error. Sorry Davide
The crash dump shows the crashing thread as: Thread 1 Crashed: 0 libdt_socket.jnilib 0x00000001017c1d22 jdwpTransport_OnLoad + 4316 1 libdt_socket.jnilib 0x00000001017c0d8d jdwpTransport_OnLoad + 327 2 libjdwp.jnilib 0x0000000100522467 Agent_OnUnload + 71685 3 libjdwp.jnilib 0x0000000100510851 Agent_OnLoad + 7045 4 libjdwp.jnilib 0x000000010050d2f0 0x100503000 + 41712 5 libjdwp.jnilib 0x0000000100511752 Agent_OnUnload + 2800 6 libjdwp.jnilib 0x0000000100510f01 Agent_OnUnload + 671 7 libclient64.dylib 0x00000001010bc5b7 JVM_IsPrimitiveClass + 6995 8 libclient64.dylib 0x00000001010026dd JNI_CreateJavaVM_Impl + 4731 9 libclient64.dylib 0x00000001010014e1 JNI_CreateJavaVM_Impl + 127 10 java 0x0000000100002dc1 0x100000000 + 11713 11 libSystem.B.dylib 0x00007fff8361d456 _pthread_start + 331 12 libSystem.B.dylib 0x00007fff8361d309 thread_start + 13 At the bottom of the crash dump, it is shown that libdt_socket.jnilib, libjdwp.jnilib, and libclient64.dylib are all part of the JVM. This shows the problem is in the "debugging" portion (as indicated by "jdwp") of your JVM and not Eclipse. A simple test will likely confirm this. After a failed attempt to start Tomcat, switch to the Debug perspective. In the Debug view, right click on the terminated Java program and select Properties. The dialog will show the Java command being executed to run Tomcat. Copy that command to a terminal session and try to execute it. You will likely encounter the same crash without Eclipse being involved. If this is a 64bit JVM you are using, you might try a 32 bit one if possible. I'm not at all familiar with the Mac or OS X, so I don't know what JVM alternatives might be available. Since the crash dump shows this isn't the fault of WTP or Eclipse, I'm resolving this as NOT_ECLIPSE. Unless the command surprisingly works in a terminal session, there isn't much more I can do to help. If it happens to work, add the full command to this bug and I'll see if there are any clues as to why.
Hi Larry thank you very much for your reply: it helped to discover the cause of the crash! By analyzing the command from the terminal I discovered that the crash was caused by a missing "localhost" entry on my hosts file! The debugger was unable to resolve it (address=localhost:58313) and this was causing the JVM to crash...

Restoring resolution to avoid confusion, since nothing was actually fixed in Eclipse. I'm glad you were able to resolve this.
