Feature openhab.tp-xtext: don’t activate org.eclipse.xtend.lib

[dilyanpalauzov]

As discussed at eclipse-xtext/xtext#3585 the XBase bundle declares that org.eclipse.xtend.lib and the transitive dependency xtend.lib.macro are required in theory, but in practice they are not needed at runtime.

By stopping openhab, cleaning the cache, changing in /usr/share/openhab/runtime/system/org/openhab/distro/distro-kar/5.1.1/distro-kar-5.1.1-features.xml and /usr/share/openhab/runtime/system/org/openhab/distro/distro/5.1.1/distro-5.1.1-features.xml the lines with org.eclipse.xtend.lib/2.40.0 and org.eclipse.xtend.lib.macro/2.40.0 to have start="false"and starting openhab, I observe that afterwards bundle:list shows:

START LEVEL 100 , List Threshold: 50
 ID │ State    │ Lvl │ Version               │ Name
────┼──────────┼─────┼───────────────────────┼─────────────────────────
140 │ Resolved │  80 │ 2.40.0.v20250825-0355 │ Xtend Runtime Library
141 │ Resolved │  80 │ 2.40.0.v20250825-0355 │ Xtend Macro Interfaces

and all my DSL rules run as expected.

• This change avoids activating org.eclipse.xtend.lib and org.eclipse.xtend.lib.macro bundles.
