Subject [jira] Commented: (DERBY-4441) Change sysinfo to print out more specific JVM information

Lily Wei commented on DERBY-4441:
---------------------------------

Thanks, Kim. The result of this fix is to add one line (java.runtime.version) to the sysinfo
output for sun jvm. For ibm jvm, it will add two line (java.runtime.version and java.fullversion)

This is the example from sun jvm output for sysinfo:
Java user dir:   c:\derby\trunk\testtmp
java.specification.name: Java Platform API Specification
java.specification.version: 1.6
java.runtime.version: 1.6.0_17-b04                                                       
                                       <<<====NEW======>>>

This is the example for ibm jvm output for sysinfo:
Java user dir:   c:\derby\trunk
java.specification.name: Java Platform API Specification
java.specification.version: 1.6
java.runtime.version: jvmwi3260sr7-20091214_49398                                        
                  <<<====NEW======>>>
java.fullversion: JRE 1.6.0 IBM J9 2.4 Windows 7 x86-32 jvmwi3260sr7-20091214_49   <<<====NEW======>>>
398 (JIT enabled, AOT enabled)

Kathey also suggests to add more info to the change of policy file. Will you mind include
that in the doc as well.

> It would be nice if sysinfo printed out more specific jvm information that is provided
with java -version. At least with the IBM jvm the system  properties java.runtime.version
and java.fullversion give some more (but not all) information.   More research is needed across
multiple jvms to tie it down.  Alternatively sysinfo could dump *all* the system property
information, but that could make the output pretty big and show irrelavant information in
some contexts.
