And since the @build doesn't 'fail', the following steps are run resulting
in confusing output.
The test where this happened is
     test/sun/management/jmxremote/bootstrap/RmiSslBootstrapTest.sh

Here are its @ directives
#
# @test @(#)RmiSslBootstrapTest.sh 1.7 07/05/05
# @summary Test RMI Bootstrap with SSL
#
# @build TestLogger RmiBootstrapTest
# @run shell/timeout=300 RmiSslBootstrapTest.sh

and here is the resulting .jtr file when the compile timed out.
