> In recent versions of Java, Runtime.exec() will hide the underlying exception unless
the code base is granted read permission on the executable file.
> Example:
> These two failures probably have the same cause:
> http://download.java.net/javadesktop/derby/javadb-5579292-report/javadb-task-3689381.html
> http://download.java.net/javadesktop/derby/javadb-5579170-report/javadb-task-3688261.html
> The former, running on an older JVM, shows the real cause:
> java.io.IOException: Cannot run program "/localhome/tendril4.2/work/install/sun-jdk-7u10-fcs-bin-b31/jdk7_10/jdk1.7.0_10/jre/bin/java":
error=12, Not enough space
> Caused by: java.io.IOException: error=12, Not enough space
> The latter, running on a more recent JVM, hides the real failure behind an AccessControlException:
> java.io.IOException: Cannot run program "/localhome/tendril4.2/work/install/sun-jdk-8-ea-bin-b93/jdk8/jdk1.8.0/jre/bin/java"
> Caused by: java.security.AccessControlException: access denied ("java.io.FilePermission"
"/localhome/tendril4.2/work/install/sun-jdk-8-ea-bin-b93/jdk8/jdk1.8.0/jre/bin/java" "read")
> We should consider changing the following grant in derby_tests.policy to include "read"
in order to make it easier to see why a test is failing:
>   // Tests need to be able to exec a java program.
>   permission java.io.FilePermission "${java.home}${/}-", "execute";
