after an OS Upgrade and a switch to Java SDK 7 i get the following stacktrace: i tried to install sdk 6 update 27, but wiht no success. There are several errors with different Message: - "An internal error occurred during: "Compute launch button tooltip"." - "Designer [8.1.0.r36x201010220706]: MALFORMED" - "Error in JDT Core during AST creation" The stacktrace looks always like this java.lang.IllegalArgumentException: MALFORMED at java.util.zip.ZipCoder.toString(Unknown Source) at java.util.zip.ZipFile.getZipEntry(Unknown Source) at java.util.zip.ZipFile.access$900(Unknown Source) at java.util.zip.ZipFile$1.nextElement(Unknown Source) at java.util.zip.ZipFile$1.nextElement(Unknown Source) at org.eclipse.jdt.internal.core.JarPackageFragmentRoot.computeChildren(JarPackageFragmentRoot.java:84) at org.eclipse.jdt.internal.core.JavaProjectElementInfo.initializePackageNames(JavaProjectElementInfo.java:252) at org.eclipse.jdt.internal.core.JavaProjectElementInfo.getProjectCache(JavaProjectElementInfo.java:225) at org.eclipse.jdt.internal.core.JavaProjectElementInfo.newNameLookup(JavaProjectElementInfo.java:290) at org.eclipse.jdt.internal.core.JavaProject.newNameLookup(JavaProject.java:2282) at org.eclipse.jdt.internal.core.JavaProject.newNameLookup(JavaProject.java:2292) at org.eclipse.jdt.internal.core.JavaProject.findType(JavaProject.java:1321) at org.eclipse.jdt.internal.core.JavaProject.findType(JavaProject.java:1228) at org.eclipse.jdt.internal.core.manipulation.JavaElementPropertyTester.test(JavaElementPropertyTester.java:155) at org.eclipse.core.internal.expressions.Property.test(Property.java:58) at org.eclipse.core.internal.expressions.TestExpression.evaluate(TestExpression.java:99) at org.eclipse.core.internal.expressions.CompositeExpression.evaluateAnd(CompositeExpression.java:53) at org.eclipse.core.internal.expressions.AdaptExpression.evaluate(AdaptExpression.java:91) at org.eclipse.core.internal.expressions.CompositeExpression.evaluateAnd(CompositeExpression.java:53) at org.eclipse.core.internal.expressions.IterateExpression.evaluate(IterateExpression.java:150) at org.eclipse.core.internal.expressions.CompositeExpression.evaluateAnd(CompositeExpression.java:53) at org.eclipse.core.internal.expressions.WithExpression.evaluate(WithExpression.java:72) at org.eclipse.core.internal.expressions.CompositeExpression.evaluateAnd(CompositeExpression.java:53) at org.eclipse.core.internal.expressions.EnablementExpression.evaluate(EnablementExpression.java:53) at org.eclipse.debug.internal.ui.launchConfigurations.LaunchShortcutExtension.evalEnablementExpression(LaunchShortcutExtension.java:287) at org.eclipse.debug.internal.ui.contextlaunching.LaunchingResourceManager.getShortcutsForSelection(LaunchingResourceManager.java:452) at org.eclipse.debug.internal.ui.contextlaunching.LaunchingResourceManager.computeLabels(LaunchingResourceManager.java:237) at org.eclipse.debug.internal.ui.contextlaunching.LaunchingResourceManager$2.run(LaunchingResourceManager.java:138) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) -- Configuration Details -- Product: Eclipse 1.3.2.20110218-0812 (org.eclipse.epp.package.jee.product) Installed Features: org.eclipse.jdt 3.6.2.r362_v20101117-0800-7z8XFW6FLFlmjJcvz03jyeFBLS_F
Sounds like a bogus entry in the classpath?
Could you please provide the whole .log file (compressed if too big)? Thanks.
Hi, As Walter assumed - it was a misconfiguration. I unchecked a system in the Java Configuration Panel and thought it would have effect on my classpath ;) But it had not. When i call my Helios Eclipse Relesae with the -vm c:\javasdk\bin library the error disappears. So it is a user error but Walter helped me finding the error. Sorry for taking your time - and thanks again. Can i close the bug ? Regards Manfred
Closing as INVALID.
Verified for 3.8M2
I have also this Problem under XP with Eclipse 4.2.2 java.lang.IllegalArgumentException: MALFORMED at java.util.zip.ZipCoder.toString(Unknown Source) at java.util.zip.ZipFile.getZipEntry(Unknown Source) at java.util.zip.ZipFile.access$900(Unknown Source) at java.util.zip.ZipFile$1.nextElement(Unknown Source) at java.util.zip.ZipFile$1.nextElement(Unknown Source) at org.eclipse.jdt.internal.core.JarPackageFragmentRoot.computeChildren(JarPackageFragmentRoot.java:86) at org.eclipse.jdt.internal.core.JavaProjectElementInfo.initializePackageNames(JavaProjectElementInfo.java:252)... it comes from an jar file in the classpath which has been recompressesed 7zip.
Created attachment 252761 [details] Log file for the "Compute launch button tooltip MALFORMED" problem
Comment on attachment 252761 [details] Log file for the "Compute launch button tooltip MALFORMED" problem I have the similar problem, It popped up a dialog which said "Compute launch button tooltip MALFORMED"
Finally, I found the problem, one of my project dependency, a jar file was broken.
