Bug 68868 Sometime a search results in the error "Memento problem" [search]
Sometimes when I do a search via Java editor popup menu References->Workspace, I get the following error in the error log: Memento problem - invalid integer for key: org.eclipse.jdt.search.resultpage.grouping value: TRUE An exception stack trace could not be found. eclipse.buildId=I200406251208 java.version=1.4.2_04 java.vendor=Sun Microsystems Inc. BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US Seems to be random. I can't find a specific search that causes the error, but it happens somewhat frequently.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/search/JavaSearchResultPage.java
private boolean isQueryRunning() {
		AbstractTextSearchResult result= getInput();
		if (result != null) {
			return NewSearchUI.isQueryRunning(result.getQuery());
		}
		return false;
	}
	public String getLabel() {
		String label= super.getLabel();
		int matchFilterCount= getMatchFiltersCount();
		int filteredMatchCount = getFilteredMatchCount();
		if (getInput() != null &&  (matchFilterCount > 0 || filteredMatchCount < getInput().getMatchCount())) {
			if (isQueryRunning()) {
				String message= SearchMessages.getString("JavaSearchResultPage.filtered.message"); 
				return MessageFormat.format(message, new Object[] { label });
			
			} else {
				String message= SearchMessages.getString("JavaSearchResultPage.filteredWithCount.message"); 
				return MessageFormat.format(message, new Object[] { label, new Integer(filteredMatchCount) });
			}
		}
		return label;
	}
	private int getMatchFiltersCount() {
		MatchFilter[] filters= getMatchFilters();
		AbstractTextSearchResult result= getInput();
		if (result == null)
			return 0;
		int filterCount= 0;
