sentry/src/main/java/io/sentry/ExternalOptions.java

+    String profileLifecycleString = propertiesProvider.getProperty("profile-lifecycle");
+    if (profileLifecycleString != null && !profileLifecycleString.isEmpty()) {
+      options.setProfileLifecycle(ProfileLifecycle.valueOf(profileLifecycleString.toUpperCase()));
+    }


Bug: Profile Lifecycle Parsing Error Handling

Missing error handling when parsing the profile-lifecycle property. If an invalid string value is provided, ProfileLifecycle.valueOf(profileLifecycleString.toUpperCase()) throws an IllegalArgumentException, causing the application to crash during initialization. Error handling should be added to prevent crashes, log a warning, and optionally fall back to a default value.

@adinauer WDYT, what should we do here. catch and ignore the exception if an unsupported value is present? That is basically what we do in getDoubleProperty in the ExternalOptions as well if its not a number we just set it to null
