Various javac tests have checks for the resource key
compiler.warn.source.no.bootclasspath
which results from using -source/-target without setting the bootclass patch. Such tests are also susceptible to other messages being generated from command line options, such as a notice that source level is obsolete.
To reduce future need to update such tests, if they were modified to pass in -Xlint:-options as appropriate, the no bootclasspath message and other options-related message would be suppressed.
