Incompatibilities between Eclipse 4.5 and 4.6

Eclipse changed in incompatible ways between 4.5 and 4.6 in ways that affect plug-ins. The following entries describe the areas that changed and provide instructions for migrating 4.5 plug-ins to 4.6. Note that you only need to look here if you are experiencing problems running your 4.5 plug-in on 4.6.

See also the list of deprecated API removals for this release.

  1. StructuredTextProcessor works in all locales
  2. Plug-in fragment org.eclipse.core.filesystem.java7 was merged into org.eclipse.core.filesystem
  3. org.eclipse.equinox.bidi major version increased to 1.0.0
  4. Differences in generated HTML for Welcome/Intro start and home pages

1. StructuredTextProcessor works in all locales

What is affected: Clients that call org.eclipse.equinox.bidi.StructuredTextProcessor#*process*(..) methods.

Description: The process/deprocess methods used to work only in certain locales, and were effectively disabled if StructuredTextEnvironment#isProcessingNeeded() returned false. This was overly restrictive and prevented bidi-aware code from working in other environments.

Action required: Clients that need to disable bidi processing should do so on a higher level. In Eclipse/JFace, bidi support is typically controlled by the application via org.eclipse.jface.util.BidiUtils#setBidiSupport(boolean) or by passing -bidi "on=y" on the command line.

2. org.eclipse.equinox.bidi major version increased to 1.0.0

What is affected: Clients that refer to org.eclipse.equinox.bidi bundle with an upper bound < 1.0.0.

Description: The org.eclipse.equinox.bidi bundle got promoted to version 1.0.0. The only functional change with respect to 0.11.0 is the change to StructuredTextProcessor.

Action required: Clients need to increase the upper bound in their dependency declarations, e.g.:

Require-Bundle: org.eclipse.equinox.bidi;bundle-version="[0.10.0,2.0.0)"

3. Plug-in fragment org.eclipse.core.filesystem.java7 was merged into org.eclipse.core.filesystem

What is affected: Features including the org.eclipse.core.filesystem.java7 fragment.

Description: Since org.eclipse.core.filesystem now requires Java 7 or higher, it can now use classes from the java.nio.file package directly without the need for a separate plug-in fragment.

Action required: Remove all references to org.eclipse.core.filesystem.java7.

4. Differences in Generated HTML for Welcome/Intro Start and Home Pages

What is affected: The HTML generated for the Welcome/Intro's start and home pages may be different.

Description: Welcome/Intro includes support to generate a page-links section containing links to the available Welcome pages. This section includes additional information on the root and standby pages. In 4.6, we also include this additional information on the pages configured as the INTRO_START_PAGE and INTRO_HOME_PAGE values too.

Action required: Any products that specify alternative start or home pages may need to revise their CSS.
