Description Jesse Glick 2017-02-10 14:50:06 UTC 
20170130 dev build with hundreds of megs consumed after closing all projects, closing all project-related windows, etc. Analyzing leaked project references in a dump, one I found with this root reference trail:

org.apache.maven.project.MavenProject
org.apache.maven.project.MavenProject.parent
org.netbeans.modules.maven.api.customizer.ModelHandle2.project
org.netbeans.modules.maven.customizer.CustomizerProviderImpl.handle2
org.openide.util.lookup.SingletonLookup.objectToLookup
org.openide.util.lookup.ProxyLookup$RealInternalData.lookups
org.netbeans.modules.projectapi.LazyLookupProviders$1Prov$1.data
java.util.ArrayList.elementData
org.netbeans.spi.project.support.DelegatingLookupImpl.currentLookups
org.netbeans.modules.maven.NbMavenProjectImpl.completeLookup
org.netbeans.modules.jumpto.file.FileDescription.project
org.netbeans.modules.jumpto.file.FileSearchAction$AsyncFileDescriptor.delegate
org.netbeans.modules.jumpto.file.FileSearchPanel.selectedFile
org.netbeans.modules.jumpto.file.FileSearchAction.panel
org.openide.loaders.FolderInstance$1R.instances
org.openide.awt.MenuBar$LazyMenu$MenuFolder.creationTask
org.openide.awt.MenuBar$MenuBarFolder.waitFor
org.openide.awt.MenuBar.menuBarFolder

It seems `FileSearchPanel` holds a strong reference to a given `Project`, so the `panel` field needs to be cleaned up. `cleanup` deletes `dialog`, which is good, but not `panel`.

That patch does not work—causes bug #270909.
