Currently when running jtreg tests on static-jdk, jtreg '-compilejdk' is set to a regular JDK binary. Populating the 'compile.jdk' system property from jtreg when creating the child process would allow `JDKToolFinder.getJDKTool()` (executing in the child process) to locate the tool from 'compile.jdk' path.
