There are still a few jar files in the runtime tests. These should use jcod or jasm instead, so there aren't binaries in the repository.

There are these:

./LoadClass/dummy.jar
./duplAttributes/test.jar
./EnclosingMethodAttr/enclMethodAttr.jar
./LocalVariableTable/testcase.jar
./ClassFile/JsrRewritingTestCase.jar
./ClassFile/testcase.jar
./7116786/testcases.jar
./classFileParserBug/emptynumbootstrapmethods.jar
./classFileParserBug/test.jar

The LoadClass/dummy.jar is testing a bad jar file, and the ClassFile/*.jar files are testing for OOM, so the .jcod file is larger than the .jar file. The other jar files can be replaced with jcod files and compiled by jtreg.
