+
+Briefly, the tests cover the following scenarios:
+1. prepre
+   set signal handlers -> create JVM -> send signals -> destroy JVM -> check signal handlers were called
+
+2. prepost
+   set signal handlers -> create JVM -> destroy JVM -> send signals  -> check signal handlers were called
+
+3. postpre
+   create JVM ->set signal handlers -> send signals -> destroy JVM -> check signal handlers were called
+
+4. postpost
+   create JVM -> set signal handlers -> destroy JVM -> send signals  -> check signal handlers were called
+
+There is one more scenario called 'nojvm'.
+In this case no jvm is created, so pure signal testing is done.
+
+Signal handlers don't do anything, so the only fact that signal handler was called is checked.
+Also 2 different ways of setting signal handlers are tested: sigaction, sigset.
+
+For 'postpre' and 'postpro' libjsig.so is used to chain signal handlers behind VM installed ones.
+
+=> Current tests cover the following cases (don't count 'nojvm' scenario):
+1. Support for pre-installed signal handlers when the HotSpot VM is created.
+2. Support for signal handler installation after the HotSpot VM is created inside JNI code
+
+
+Notes:
+
+SIGQUIT, SIGTERM, SIGINT, and SIGHUP signals cannot be chained.
+If the application needs to handle these signals, the -Xrs option needs
+to be specified. So, test these signals only with -Xrs flag.
+
+On Linux and Mac OS X, SIGUSR2 is used to implement suspend and resume. So,
+don't test SIGUSR2 on Linux and Mac OS X.
+
+SIGJVM1 and SIGJVM2 exist only on Solaris and are reserved for exclusive use
+by the JVM. So don't test SIGJVM1 and SIGJVM2.
