20021216 everytime you do this: 1. open java editor pref page 2. close the pref page you end up having allocated and not disposed 8 colors 1 is allocated like this at org.eclipse.jdt.internal.ui.preferences.JavaEditorPreferencePage.createColor(JavaEditorPreferencePage.java:560) at org.eclipse.jdt.internal.ui.preferences.JavaEditorPreferencePage.initializeViewerColors(JavaEditorPreferencePage.java:534) at org.eclipse.jdt.internal.ui.preferences.JavaEditorPreferencePage.createPreviewer(JavaEditorPreferencePage.java:493) at org.eclipse.jdt.internal.ui.preferences.JavaEditorPreferencePage.createSyntaxPage(JavaEditorPreferencePage.java:433) at org.eclipse.jdt.internal.ui.preferences.JavaEditorPreferencePage.createContents(JavaEditorPreferencePage.java:942) at org.eclipse.jface.preference.PreferencePage.createControl(PreferencePage.java:209) and the other 7 are allocated like this: at org.eclipse.jdt.internal.ui.text.JavaColorManager.getColor(JavaColorManager.java:62) at org.eclipse.jdt.internal.ui.text.JavaColorManager.getColor(JavaColorManager.java:85) at org.eclipse.jdt.internal.ui.text.AbstractJavaScanner.addToken(AbstractJavaScanner.java:90) at org.eclipse.jdt.internal.ui.text.AbstractJavaScanner.initialize(AbstractJavaScanner.java:75) at org.eclipse.jdt.internal.ui.text.java.JavaCodeScanner.<init>(JavaCodeScanner.java:126) at org.eclipse.jdt.ui.text.JavaTextTools.<init>(JavaTextTools.java:80) at org.eclipse.jdt.internal.ui.preferences.JavaEditorPreferencePage.createPreviewer(JavaEditorPreferencePage.java:486) at org.eclipse.jdt.internal.ui.preferences.JavaEditorPreferencePage.createSyntaxPage(JavaEditorPreferencePage.java:433) at org.eclipse.jdt.internal.ui.preferences.JavaEditorPreferencePage.createContents(JavaEditorPreferencePage.java:942) at org.eclipse.jface.preference.PreferencePage.createControl(PreferencePage.java:209)
