cleanupStaleTempJarFiles

public static void cleanupStaleTempJarFiles()

Cleanup any stale temporary agent jar files in the defined temp folder if a threshold has been configured via the NEW_RELIC_TEMP_JARFILE_AGE_THRESHOLD_HOURS env variable or the newrelic.config.temp_jarfile_age_threshold_hours system property.

A file is eligible to be deleted if it starts with one of the internal agent jar prefixes ("agent-bridge", "newrelic-api", etc.), has the ".jar" extension and is older than the specified cutoff value.

Description copied from interface: EmbeddedJarFiles

Returns a jar file created by reading the contents of a jar embedded inside of the agent jar and writing it out to a temp file. The result is cached so that multiple calls to this api for a given jar name reuse the same temp file.
