Description

When printing text by Java7, some letters are overlapped.
For example, graphics2d.drawString(Japanse+English) causes the
Japanese letters and English letters overlapping.
This is a regression from Java6, because Java6 doesn't have 
this problem.

I can reproduce this from JDK 7 b08 onwards. My guess is that its due to a bug in the fix for 6425068 : Mismatch between the drawing width and font metrics One part of that fix was to assign glyph positions in certain cases. If we aren't adding the start position of a new run then you would get this overlapping

To reproduce the bug, 1. Compile DrawPanel.java, Print.java and Frame.java 2. Exec Print.java - Japanese text and English text overlap (see print_bug.png attached) 3. Exec Frame.java - looks work fine. DrawPanel.java have Japanese strings in the source in UTF-8 encoding. Please compile it on UTF-8 locale.
