Sometimes this issue leads to 
{code}
Error
Unhandled event loop exception

{code}
and only restart of whole eclipse can helps.

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}
