I've gotten the same error (although when redrawing using a themed scroll bar, the point where the exception is thrown is the same). !ENTRY org.eclipse.e4.ui.css.swt.theme 4 0 2017-10-13 09:53:45.373 !MESSAGE 36 !STACK 0 java.lang.ArrayIndexOutOfBoundsException: 36 at org.eclipse.swt.custom.StyledTextRenderer.getTextLayout(StyledTextRenderer.java:765) at org.eclipse.swt.custom.StyledTextRenderer.getTextLayout(StyledTextRenderer.java:719) at org.eclipse.swt.custom.StyledText.getOffsetAtPoint(StyledText.java:4525) at org.eclipse.swt.custom.StyledText.doMouseLinkCursor(StyledText.java:2779) at org.eclipse.swt.custom.StyledText.doMouseLinkCursor(StyledText.java:2776) at org.eclipse.swt.custom.StyledText.redraw(StyledText.java:7564) at org.eclipse.e4.ui.internal.css.swt.dom.scrollbar.StyledTextThemedScrollBarAdapter$StyledTextPaintListener.redrawScrollBars(StyledTextThemedScrollBarAdapter.java:662) at org.eclipse.e4.ui.internal.css.swt.dom.scrollbar.AbstractThemedScrollBarAdapter.setMouseNearScrollScrollBarWidth(AbstractThemedScrollBarAdapter.java:482) at org.eclipse.e4.ui.css.swt.dom.StyledTextElement.setMouseNearScrollScrollBarWidth(StyledTextElement.java:59) at org.eclipse.e4.ui.css.swt.properties.custom.CSSPropertyStyledTextScrollbarSWTHandler.applyCSSProperty(CSSPropertyStyledTextScrollbarSWTHandler.java:65) at org.eclipse.e4.ui.css.core.impl.engine.AbstractCSSEngine.applyCSSProperty(AbstractCSSEngine.java:766) at org.eclipse.e4.ui.css.core.impl.engine.AbstractCSSEngine.applyStyleDeclaration(AbstractCSSEngine.java:552) at org.eclipse.e4.ui.css.core.impl.engine.AbstractCSSEngine.applyStyles(AbstractCSSEngine.java:426) at org.eclipse.e4.ui.css.core.impl.engine.AbstractCSSEngine.applyStyles(AbstractCSSEngine.java:367) at org.eclipse.e4.ui.css.core.impl.engine.AbstractCSSEngine.applyStyles(AbstractCSSEngine.java:443) Note: raising to critical: after this happens the editor becomes unusable. Note 2: marking all (the original was on Mac and I had this on Windows, so, it appears it may happen anywhere).
Can you post steps to reproduce?
Unfortunately I can't reproduce this reliably (seen it happen twice in many months, so, it doesn't happen often -- this time it happened right after doing a save in PyDev while having a code formatter on -- so, it changed the text just before the save operation). Still, can't seem to find a way to reliably trigger it (what I know is that when it happens the editor becomes unusable and has to be closed/reopened).
