Build Identifier: eclipse.buildId=M20100211-1343 java.lang.OutOfMemoryError: Java heap space at java.lang.String.<init>(String.java:208) at com.sun.org.apache.xerces.internal.xni.XMLString.toString(XMLString.java:226) Reproducible: Always Steps to Reproduce: 1.Start Eclipse 2.Go to Help 3.Select Check for updates

Moving to Equinox/p2
Well, it is telling you that you ran out of memory in the Java VM. Just because it happened when checking for updates does not mean that it was p2 that took all your memory. The stack trace reveals that it is simply trying to parse an XML document. If you have lots of things installed in your IDE already, you probably want to increase the max memory available to the VM. Does this happens when checking for updates on a freshly started IDE where no editors are open? Do this: 1. Close all open editors in your IDE 2. Exit 3. Start 4. Check for updates The reason for doing this is that if you have lots of things open, a lot of memory can have been consumed already. Some plugins could be buggy and leak memory, etc. Second thing to check is if you are trying to read a repository that has errors or simply is *enormous". I am tempted to close as "not-p2", but if this happens on a fresh Helios configuration while only contacting eclipse repositories it is something that should be looked into. Can you provide more details?
Thank you for your reply. In fact I have gradually increased Xmx from 384 to 768 MB, ie C:\Programmi\eclipse-SDK-3.5.2-win32\eclipse\eclipse.exe -vmargs Xmx768M If the stack trace is not enough, what diagnostic tools could I use to look at what is happening? Since this is a fresh installation - I have been using 3.4.2 until last Thursday - querying sites for updates and plugins is the first thing I do after having started Eclipse. I'd be really obliged if you could help me in performing a real troubleshooting. Sincerely, Massimo
Trying to install Eclipse Memory Analyzer (MAT) always fail: eclipse.buildId=M20100211-1343 java.version=1.5.0_17 java.vendor=Sun Microsystems Inc. BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=it_IT Command-line arguments: -os win32 -ws win32 -arch x86 Error Wed Jul 07 11:21:06 CEST 2010 No repository found at http://download.eclipse.org/technology/mat/0.8/update-site/. How can I check what wastes all the JVM virtual memory? regards MR
Found repository for MAT version 1.0, downloaded. Install procedure fails for lack of heap space. I understand that something in my IDE is poorly handled by Eclipse, which wastes memory instead of reporting an error. How can I detect what is wrong? Thanks, regards MR
