Every time Oracle’s HTTPClient opens an SSL socket, the java.security.Security.getAlgClassName()
is unzipping a JAR file. This is resulting in higher than expected CPU cycles and slower performance.

SUN’s JDK 1.4.1 src for java.security.Security class does not contain the getAlgClassName method.

Looking at the java.security configuration file on AIX, the file shows:


The sun.security.provider.Sun is not included in the IBM runtime jar.
If the sun.security.provider.Sun entry is removed from the java.security,
CPU performance increases (45.44% CPU) when compared to the 62.42% CPU before the change.
