Document

Creates a new Java abstract syntax tree Following option keys are significant:

"org.eclipse.jdt.core.compiler.source" indicates the api level and source compatibility mode (as per JavaCore) - defaults to 1.3
- "1.3" means the source code is as per JDK 1.3 and api level #JLS3 .
- "1.4", "1.5", "1.6", "1.7" "1.8" implies the respective source JDK levels 1.4, 1.5, 1.6, 1.7 and api level #JLS4 .
- "1.8" implies the respective source JDK level 1.8 and api level #JLS8 .
- "9", "10", "11", "12" and "13" implies the respective JDK levels 9, 10, 11, 12 and 13 and api levels #JLS9 , #JLS10 , #JLS11 , #JLS12 and #JLS13 .
- Additional legal values may be added later.

"org.eclipse.jdt.core.compiler.problem.enablePreviewFeatures" - indicates whether the preview is enabled or disabled legal values are "enabled" and "disabled" implying preview enabled and disabled respectively.
