Bug 58921 Texts created with unsupported styles
- org.eclipse.jdt.internal.ui.text.AbstractInformationControl.createFilterText creates a Text with style SWT.FLAT - org.eclipse.jdt.internal.ui.filters.CustomFiltersDialog.createCheckBoxList creates a Text with style SWT.VERTICAL (perhaps V_SCROLL was meant?)
