NonStop Server for Java 5.0 Programmer's Reference

POSIX Threads
NonStop Server for Java 3.1.x and earlier versions used OSS POSIX threads (product number
T5819) that conformed to an earlier standard (Draft 4) for POSIX threads. NonStop Server for
Java 4 and 5 use Standard POSIX Threads (product number T1248), which conforms to IEEE
POSIX Standard 1003.lc.
The POSIX threads calls in T1248 have changed to conform to the standard; therefore, any
native code for NonStop Server for Java 3.1.x applications that makes POSIX threads calls
might have to change to use the standard pthread routine. For more information, see
Appendix D in the Open System Services Porting Guide, which contains a list of differences
between the POSIX thread routines in T5819 and the routines in T1248.
Additionally, you must change any JNI code that made calls to routines beginning with cma… to
use the Wrapper or Development Toolkit routines (spt….) supplied with T1248.
NOTE: Any user-developed code that makes such POSIX threads calls must
change.
Directories of Binary Files Moved
If your NonStop Server for Java programs have references to bin/oss/posix_threads in
Pathway configuration files or elsewhere, you must change them to use the NonStop Server for
Java 5 installation bin directory.
In NonStop Server for Java 3.1.x or earlier versions, the bin and jre/bin directories
contained a shell script that ran the real executable that was located in
bin/oss/posix_threads. In the NonStop Server for Java 5 version, the bin directory
contains the real executable, no shell script wrapper, and no bin/oss/posix_threads
directory. The jre/bin directory contains the executables in the bin directory.
Character Handling
With NonStop Server for Java 5, character handling is based on version 4.0 of the Unicode
standard. This new basis affects the Character and String classes in the java.lang
package, the collation and bidirectional text analysis functionality in the java.text
package, character classes in the java.util.regex package, and many other parts of
the J2SE. Support for supplementary characters has been specified by the Java Specification
Request (JSR) 204 expert group and implemented throughout the J2SE. See the article
