It seems some of the openjdk-6 tests are unstable.  The non-exec-stack
change builds showed the following test differences with the updated
patch against 6b16-1.6~pre1-0ubuntu1:

-Passed: java/awt/grab/EmbeddedFrameTest1/EmbeddedFrameTest1.java
+FAILED: java/awt/grab/EmbeddedFrameTest1/EmbeddedFrameTest1.java

-FAILED: sun/security/ssl/javax/net/ssl/NewAPIs/SessionCacheSizeTests.java
+Passed: sun/security/ssl/javax/net/ssl/NewAPIs/SessionCacheSizeTests.java

Status in “openjdk-6” package in Ubuntu: Triaged

Bug description:
Java is marked to have an executable stack[1].  This is potentially dangerous, and is simply an oversight from one of the compiled assembly files.  Adding stack markings to the assembly solves the issue.
