Virtual Machine for the Java Platform on <strong>ClearPath</strong> <strong>OS</strong> <strong>2200</strong> JProcessor (JPJVM)<br />
<strong>ClearPath</strong> <strong>OS</strong> <strong>2200</strong> <strong>Release</strong> 12.1<br />
JVM Level 4R2A<br />
Migration<br />
The following statement in quotes from section 3.2 Environment Variables in the JVM<br />
user guide for <strong>ClearPath</strong> <strong>OS</strong> <strong>2200</strong> <strong>Release</strong> 12.0 is no longer valid <strong>and</strong> is removed from<br />
the JVM user guide for <strong>ClearPath</strong> <strong>OS</strong> <strong>2200</strong> <strong>Release</strong> 12.1: “The FILE.ENCODING value<br />
should be added only if the default coded character set (CCS) does not correspond to the<br />
CCS associated with the default locale or the locale in force when the JVM on <strong>OS</strong> <strong>2200</strong><br />
is initiated.” Setting the system property to anything other than one of the Sun provided<br />
st<strong>and</strong>ard character sets is dangerous. It can cause JVM initialization failures in Java SE<br />
1.5. Sun added a new java.nio charset mechanism in Java J2SE 1.4. Sun left the old<br />
deprecated converter mechanism in place, but its usefulness has eroded over time. The<br />
new java.nio charset mechanism should be used for Unisys provided charsets.<br />
<strong>ClearPath</strong> <strong>OS</strong> <strong>2200</strong> <strong>Release</strong> 12.0<br />
JVM Level 4R2<br />
Compatibility<br />
JVM 4R2 requires CIFS 6R3 or higher.<br />
5.54. Virtual Machine for the Java Platform on<br />
<strong>ClearPath</strong> <strong>OS</strong> <strong>2200</strong> JProcessor (JPJVM)<br />
<strong>ClearPath</strong> <strong>OS</strong> <strong>2200</strong> <strong>Release</strong> 12.1<br />
JPJVM Level 6.1<br />
Migration<br />
The following statement in quotes from section 3.2 Environment Variables in the CP12.0<br />
JPJVM user guide is no longer valid <strong>and</strong> is removed from the CP12.1 JPJVM user guide.<br />
“The FILE.ENCODING value should be added only if the default coded character set<br />
(CCS) does not correspond to the CCS associated with the default locale or the locale in<br />
force when the JVM on <strong>OS</strong> <strong>2200</strong> is initiated.” Setting the system property to anything<br />
other than one of the Sun provided st<strong>and</strong>ard character sets can cause JVM initialization<br />
failures in Java SE 1.5. In Java SE 1.6, it is silently ignored <strong>and</strong> UTF-8 is used instead of<br />
what was specified. Sun Microsystems added a new java.nio charset mechanism in Java<br />
J2SE 1.4. Sun Microsystems left the old deprecated converter mechanism in place, but<br />
its usefulness has eroded over time. The <strong>ClearPath</strong> <strong>OS</strong> <strong>2200</strong> JProcessor JVM only<br />
supports the new java.nio charset mechanism for Unisys provided charsets.<br />
<strong>ClearPath</strong> <strong>OS</strong> <strong>2200</strong> <strong>Release</strong> 12.0<br />
JPJVM Level 6.0<br />
Compatibility<br />
The CIFS utility, ZIPUT, requires use of the <strong>OS</strong> <strong>2200</strong> JVM which can be installed<br />
concurrently with JPJVM. The I18N proprietary classes have been removed.<br />
