Its purpose is +to make possible the use of CTW in product builds. + +DEPENDENCES + +The tool depends on Whitebox API. Assumed, that the sources of whitebox are +located in '../whitebox' directory. + +BUILDING + +Simple way to build, just type 'make'. + +Makefile uses environment variables 'ALT_BOOTDIR', 'BOOTDIR' as root-dir of jdk +that will be used for compilation and creating jar. + +On successful building 'ctw.jar' will be created. + +RUNNING + +Since the tool uses WhiteBox API, options 'UnlockDiagnosticVMOptions' and +'WhiteBoxAPI' should be specified, and 'wb.jar' should be added to +boot-classpath: + $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar + +Arguments can be paths to '.jar, '.zip', '.lst' files or directories with +classes, that define which classes will be compiled: + - '.jar', '.zip' files and directories are interpreted like in classpath +(including '<dir>/*' syntax) + - '.lst' files -- files with class names (in java notation) to compile. +CTW will try to find these classes with default class loader, so they should +be located in classpath. + +Without arguments it would work as old version of CTW: all classes in +boot-classpath will be compiled, excluding classes in 'rt.jar' if 'rt.jar' isn't +first in boot-classpath. + +Due CTW's flags also are not available in product builds, the tool uses +properties with the same names: + - 'CompileTheWorldPreloadClasses' -- type:boolean, default:true, description: +Preload all classes used by a class before start loading + - 'CompileTheWorldStartAt' -- type:long, default:1, description: First class +to consider + - 'CompileTheWorldStopAt' -- type:long, default:Long.MAX_VALUE, description: +Last class to consider + +Also it uses additional properties: + - 'sun.hotspot.tools.ctw.verbose' -- type:boolean, default:false, +description: Verbose output, adds additional information about compilation + - 'sun.hotspot.tools.ctw.logfile' -- type:string, default:null, +description: Path to logfile, if it's null, cout will be used. + +EXAMPLES + +compile classes from 'rt.jar': + $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar ${JAVA_HOME}/jre/lib/rt.jar + +compile classes from all '.jar' in './testjars' directory: + $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar ./testjars/* + +compile classes from './build/classes' directory: + $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar ./build/classes + +compile only java.lang.String, java.lang.Object classes: + $ echo java.lang.String > classes.lst + $ echo java.lang.Object >> classes.lst + $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar classes.lst +
