Build 2.1-M3 Accessing the signature of a field member uses a public Signature entry point, and thus ends up rescanning the signature to check it is valid. However, since it came through an info, it is guaranteed to be already correct. Trusted clients should benefit from priviledged signature computation. ================== at org.eclipse.jdt.internal.compiler.parser.Scanner.<init> (Scanner.java:134) at org.eclipse.jdt.internal.compiler.parser.Scanner.<init> (Scanner.java:169) at org.eclipse.jdt.core.Signature.createCharArrayTypeSignature (Signature.java:438) at org.eclipse.jdt.core.Signature.createTypeSignature (Signature.java:417) at org.eclipse.jdt.internal.core.SourceFieldElementInfo.getTypeSignature (SourceFieldElementInfo.java:51) at org.eclipse.jdt.internal.core.SourceField.getTypeSignature (SourceField.java:55) at org.eclipse.jdt.internal.ui.viewsupport.JavaElementLabels.getFieldLabel (JavaElementLabels.java:426) at org.eclipse.jdt.internal.ui.viewsupport.JavaElementLabels.getElementLabel (JavaElementLabels.java:295) at org.eclipse.jdt.internal.ui.viewsupport.JavaElementLabels.getElementLabel (JavaElementLabels.java:272) at org.eclipse.jdt.internal.ui.viewsupport.JavaElementLabels.getTextLabel (JavaElementLabels.java:257) at org.eclipse.jdt.internal.ui.viewsupport.JavaUILabelProvider.getText (JavaUILabelProvider.java:118) at org.eclipse.jface.viewers.DecoratingLabelProvider.getText (DecoratingLabelProvider.java:100) at org.eclipse.jface.viewers.TreeViewer.doUpdateItem(TreeViewer.java:82) at org.eclipse.jface.viewers.AbstractTreeViewer.doUpdateItem (AbstractTreeViewer.java:353) at org.eclipse.jface.viewers.StructuredViewer.updateItem (StructuredViewer.java:1132) at org.eclipse.jface.viewers.AbstractTreeViewer.internalRefresh (AbstractTreeViewer.java:833) at org.eclipse.jface.viewers.AbstractTreeViewer.internalRefresh (AbstractTreeViewer.java:847) at org.eclipse.jface.viewers.AbstractTreeViewer.internalRefresh (AbstractTreeViewer.java:847) at org.eclipse.jface.viewers.AbstractTreeViewer.labelProviderChanged (AbstractTreeViewer.java:935) at org.eclipse.jface.viewers.ContentViewer.handleLabelProviderChanged (ContentViewer.java:155) at org.eclipse.jface.viewers.StructuredViewer.handleLabelProviderChanged (StructuredViewer.java:524) at org.eclipse.jdt.internal.ui.javaeditor.JavaOutlinePage$JavaOutlineViewer.handleL abelProviderChanged(JavaOutlinePage.java:635) at org.eclipse.jface.viewers.ContentViewer$1.labelProviderChanged (ContentViewer.java:68) at org.eclipse.ui.internal.DecoratorManager.fireListeners (DecoratorManager.java:141) at org.eclipse.ui.internal.DecoratorManager.labelProviderChanged (DecoratorManager.java:431) at org.eclipse.jface.viewers.LabelProvider.fireLabelProviderChanged (LabelProvider.java:54) at org.eclipse.team.internal.ccvs.ui.CVSDecorator.access$2 (CVSDecorator.java:1) at org.eclipse.team.internal.ccvs.ui.CVSDecorator$3.run (CVSDecorator.java:406) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:31) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages (Synchronizer.java:94) -

*** Bug 27330 has been marked as a duplicate of this bug. ***
this would be a nice improvement calls to Scanner() (via getTypeSignature) account for 23% of time needed to open a java editor
Changed implementation to not use Scanner at all and to not create unneeded objects.
Verified.
