> ImageDescriptor -> createImage() - from documentation to this function:
> {code}
> * Creates and returns a new SWT image for this image descriptor. Note that
> * each call returns a new SWT image object. The returned image must be
> * explicitly disposed using the image's dispose call. The image will not be
> * automatically garbage collected. ...
> {code}
> here you create images, but did not dispose it:
> {code}
> at org.jboss.tools.vpe.editor.toolbar.format.TextFormattingToolBar.createItems(TextFormattingToolBar.java:180)
> {code}
