NAME

Manual page of ’java’ wrapper for SableVM - free (LGPL) Java virtual machine

SYNOPSIS

java-sablevm [OPTION]... CLASSNAME [ARGUMENT]...

DESCRIPTION

[-]-addclasspath ADDEDCLASSPATH
  appends ADDEDCLASSPATH at the end of CLASSPATH (note that parameters’ order is important!)
[-]-cp CLASSPATH, [-]-classpath CLASSPATH, [-]-classpath=CLASSPATH
  set CLASSPATH for program to be run (overrides value of CLASSPATH environment variable)
-DPROPERTY=VALUE
  set PROPERTY value to VALUE
-h, [-]-help, -? show help (not implemented yet, see manual page)
-jar FILE
  execute content of FILE as a jar type file (requires unzip utility installed); note that you can’t specify CLASSNAME in this case
[-]-showversion
  show version (like -V) and continue execution
-v, [-]-verbose
  enable all verbose options (might *flood* you if SableVM is compiled with debugging options)
[-]-verbose-gc
  enable verbose garbage collection
[-]-verbose[:]jni
  enable verbose Java Native Interface
-V, [-]-version
  show version information, including some compilation options
-Xbootclasspath:/pa/th, -Xbootclasspath/p:/pa/th, -Xbootclasspath/a:/pa/th
  set the value of the boot classpath, prepend or append a value to it
-Xgnuclasspath:/dir/ectory
  sets the location of GNU Classpath libraries (not sablevm-classpath); NOTE: due to ever-changing nature of VM <-> Classpath interfaces you might need to use the latest SableVM snapshot if you want to run the latest GNU Classpath CVS directly with SableVM; This option is meant mainly for Java Virtual Machine and GNU Classpath developers and advanced users.
-- end of options marker - CLASSNAME (if any) and ARGUMENTS (if any) should follow

RECOGNIZED ENVIRONMENTAL VARIABLES

CLASSPATH
  used as the classpath for the program being started, unless -cp was specified
LD_LIBRARY_PATH
  used to search for location of native java libraries, incompatible with setting java.library.path property

OPTIONS IGNORED

[-]-debug, -Xdebug, (extended debug options)
-ss VALUE, (maximal stack size)
-ms VALUE, (initial heap size)
-ms VALUE, (maximum heap size)
-X[...], (other extended option)
-noverify, (turn off bytecode verifier)
-verbosemem, (verbose memory allocation)
-verbosegc, (verbose memory allocation)
-verbosejit, (verbose memory allocation)
-verbose[...], (other verbose option)
-vmdebug opt1[,opt2...], (other debug option)
  All the above options are recognized by java-sablevm wrapper and ignored. Their handling is either not implemented by the wrapper or by sablevm binary (and thus they can not be translated to options sablevm is able to recognize).

DEBUGGING PROPERTIES

The below properties are only usable when SableVM was compiled with --enable-debugging-features, which is not the case ie. for binary distributions.
sablevm.verbose.methods
  when operating on a binary compiled with debugging features - setting this property to true outputs names of every method that is to be executed
sablevm.verbose.instructions
  when operating on a binary compiled with debugging features - setting this property to true outputs names of every instruction that is to be executed (WARNING: expect flood!!!)
sablevm.verbose.synchronization
  when operating on a binary compiled with debugging features - setting this property to true causes SableVM to dump a stack trace on every locking contention and on fat lock acquisition.
