JavaTest Message: shutting down test

A similar bug 6418004 was reported and fixed for JDK 6.
Comments
EVALUATION This is as suspected a duplicate of 6418004: java/awt/font/StyledMetrics/StyledMetrics.java fails on Vista The test itself is buggy and was fixed in the JDK 6 workspace. The bug remains in the JDK 5 workspace. Running the JDK 6 version of the test on 1.5 update 10, the test passes. One minor modification to the test needs to be made so that it compiles on 1.5. The modification is to avoid using a 1.6 API : sccs diffs StyledMetrics.java ------- StyledMetrics.java ------- 194c194 < g2d.getFontMetrics().getFontRenderContext(); --- > g2d.getFontRenderContext();
