[github-actions]

Bumps scripts/update-java.ps1 from 8.45.0 to 8.46.0.

Auto-generated by a dependency updater.

Changelog

8.46.0

Behavioral Changes

• Collections returned by scope (e.g. getBreadcrumbs, getTags, getAttachments) are shared state and should not be mutated. (#5541)
  • Previously, when going through CombinedScopeView, we were returning a copy where mutations didn't show up in the underlying scopes.
  • This has now changed in order to reduce SDK overhead.
• Date objects returned by SDK data model getters are shared state and should not be mutated. (#5603)
  • Previously, these getters returned defensive copies for some date fields.
  • This has now changed in order to reduce SDK overhead.

Performance

• Reduce writer buffer size from 8192 to 512 (#5544)
• Remove redundant event map copies (#5536)
• Optimize combined scope by adding an early return if only one scope has data (#5541)
• Reduce model access overhead by avoiding defensive Date copies in SDK data model getters. (#5603)
• Reduce timestamp parsing and formatting overhead with Sentry-specific ISO-8601 handling. (#5602)
• Reduce JSON serialization overhead by creating the reflection serializer only when unknown-object fallback serialization is needed. (#5601)
• Reduce JSON serialization overhead by allocating reflection cycle-tracking state only when reflection serialization is used. (#5600)
• Reduce context serialization overhead by sorting key snapshots with arrays instead of temporary lists. (#5599)
• Reduce breadcrumb allocation overhead by creating the Breadcrumb data map only when data is added. (#5598)
• Reduce JSON serialization overhead by lowering the initial JsonWriter nesting stack size while preserving on-demand growth. (#5591)
• Reduce timestamp helper overhead by replacing unnecessary Calendar usage in DateUtils with direct Date creation. (#5589)
• Reduce Android startup overhead by using the default timezone directly on older devices or when no timezone info is available in the locale. (#5587)

Features

• On Android 15+ (API 35), the standalone app.start transaction now reports why the OS started the process via app.vitals.start.reason trace data (e.g. launcher, broadcast, service, content_provider), derived from ApplicationStartInfo.getReason(). You can search and group by this attribute in the Trace Explorer. (#5552)

8.43.3

Fixes

• Fix crash when getHistoricalProcessStartReasons is called from an isolated or wrong-userId process (#5597)

+### Behavioral Changes

+- Collections returned by scope (e.g. `getBreadcrumbs`, `getTags`, `getAttachments`) are shared state and should not be mutated. ([#5541](https://github-redirect.dependabot.com/getsentry/sentry-java/pull/5541))
+  - Previously, when going through `CombinedScopeView`, we were returning a copy where mutations didn't show up in the underlying scopes.
+  - This has now changed in order to reduce SDK overhead.
+- `Date` objects returned by SDK data model getters are shared state and should not be mutated. ([#5603](https://github-redirect.dependabot.com/getsentry/sentry-java/pull/5603))
+  - Previously, these getters returned defensive copies for some date fields.
+  - This has now changed in order to reduce SDK overhead.

 ## 8.45.0
 
+### Features
+
+- On Android 15+ (API 35), the standalone `app.start` transaction now reports why the OS started the process via `app.vitals.start.reason` trace data (e.g. `launcher`, `broadcast`, `service`, `content_provider`), derived from `ApplicationStartInfo.getReason()`. You can search and group by this attribute in the Trace Explorer. ([#5552](https://github-redirect.dependabot.com/getsentry/sentry-java/pull/5552))
+
 ### Fixes
 
 - Use `System.nanoTime()` for cron check-in duration measurement to avoid incorrect durations from wall-clock adjustments ([#5611](https://github-redirect.dependabot.com/getsentry/sentry-java/pull/5611))
 -41,7 +71,6 
   - Emits a transaction named `App Start` with op `app.start`, carrying the existing app start measurements and phase spans (`process.load`, `contentprovider.load`, `application.load`, activity lifecycle spans) as direct children of the root
   - The standalone transaction shares the same `traceId` as the first `ui.load` activity transaction so they remain linked in the trace view
   - Also covers non-activity starts (broadcast receivers, services, content providers)
-  - On Android 15+ (API 35), the standalone `app.start` transaction reports why the OS started the process via `app.vitals.start.reason` trace data (e.g. `launcher`, `broadcast`, `service`, `content_provider`), derived from `ApplicationStartInfo.getReason()`. You can search and group by this attribute in the Trace Explorer. ([#5552](https://github-redirect.dependabot.com/getsentry/sentry-java/pull/5552))
