JDK 8 Profiles Implementation Notes

Updated: 2013/11/29

These implementation notes should be read in conjunction with the proposed contents listed in JEP-161

The "profiles" build target is Linux-only at this time

All profiles

• Builds include the java launcher and keytool.
• Builds only include the 4 standard protocol handlers (file, jar, http, https). The ftp and mailto protocol handlers are only included in the JRE/JDK build.
• Include javax.script but do not include any script engines (would need to copy in Nashorn from a JDK build to get a "js" engine).
• Builds include localedata.jar so that all optional Locales are available.
• Builds do not include the CLDR locale service provider.
• Builds only contain the charsets that are in the sun.nio.cs package (includes the 6 standard charsets); The extended charsets (double-byte and IBM) are only included in the JRE/JDK build.
• Builds include the SUN, SunJCE, SunRsaSign, SunJSSE, SunEC, and SunPKCS11 security providers (although SunPKCS11 will not be configured by default).
• Builds do not include the DNS-only name service provider for InetAddress.
• Builds do not include the ZIP file system provider (zipfs).

compact1 and compact2

• The http and https protocol handlers only support Basic and Digest authentication.
• SSL/TLS (JSSE) does not support/negotiate Kerberos cipher suites.
• The only CertStore type supported is the standard "Collection" type.

compact2

• Adds rmiregistry and rmid.
• Adds the JDK-specific http server API (com.sun.net.httpserver).

compact3

• Adds the SunJGSS, SunSASL, XMLDSig and SunPCSC security providers.
• Adds NTLM and SPNEGO based Kerberos authentication to the http and https protocol handlers.
• Adds support for Kerberos cipher suites to SSL/TLS (JSSE).
• Adds CertStore implementation type "LDAP".
• Builds include the JNDI LDAP, RMI Registry and DNS service providers. The Cos Naming service provider is only included in the JRE/JDK build.
• The JMX Remote API only supports the default RMI transport (JRMP). The IIOP transport is additionally supported by the JRE/JDK build.
• Include javax.tools but does not include a compiler implementation unless tools.jar is copied from a JDK image.
• Adds the Java Smart Card I/O API (JSR-268, javax.smartcardio).
• Adds the JDK-specific management extensions (com.sun.management).
• Adds the JDK-specific API to JAAS (com.sun.security.auth) but with com.sun.security.auth.callback.DialogCallbackHandler omitted.
• Adds the JDK-specific GSS API (com.sun.security.jgss).
• Adds the JDK-specific SCTP API (com.sun.nio.sctp).
• Adds the JDBC Rowset RI (com.sun.rowset).
