Details of all changes by API and date

Java Platform API

Added Specification.getDisplayName returning the user friendly name of the platform specification.

Jun 13 '12; API spec. version: 1.26; affected top-level classes: Specification; made by: tzezula; issues: #198834
Added Specification.getDisplayName returning the user friendly name of the platform specification.

Apr 12 '06; API spec. version: 1.9; made by: jglick

JavaPlatformManager.getDefaultPlatform could formerly return null, in case no installed providers returned an instance; typically this would be due to some storage problem. In the interests of robustness, it will now as a fallback return a simple platform instance corresponding the JRE hosting the NetBeans code. Optional capabilities may be missing so avoid relying on this fallback platform implementation.


Code which previously handled null return values but expected any returned platform instance to meet certain criteria, such as having JDK tool bindings, may be broken.

Added new CustomPlatformInstall implemented by the platform installers which does not use the file chooser to select new platform

Jul 27 '05; API spec. version: 1.5; affected top-level classes: CustomPlatformInstall GeneralPlatformInstall; made by: tzezula; issues: #61475

There are some platform installers which does not use the local disk as source of the java platform, for example they download the java platform from the web. Such installers cannot use the current PlatformInstall which is file oriented. The CustomPlatformInstall allows to platform install provider to implement its own way of installing the new platform. The PlatformInstall is still supported. If the module provides the PlatformInstall in the global lookup, the java platform module does the java platform chooser for it, the behavior is not changed. If the module provides the CustomPlatformInstall in the global lookup, it has to do the platform selection by itself.

Switched to major release version 1

Dec 22 '04; API spec. version: 1.3; made by: jglick; issues: #51468

To indicate that this is now considered a stable API, the major release version was incremented to 1 from 0.


Clients should begin requesting the new version to avoid a warning at startup.
