[QOS.CH (JIRA)]

Title: Message Title

Øyvind Horneland commented on LOGBACK-1623   Re: NPE in ThrowableProxy in 1.2.11 if extractSupressedThrowables returns null The check for length in https://github.com/qos-ch/logback/blob/v_1.2.11/logback-classic/src/main/java/ch/qos/logback/classic/spi/ThrowableProxy.java#L99 can be reached with the implementation of extractSupressedThrowables that supports returning null so there is a theoretical path there, but dunno if it in reality ever will hit anything other than https://github.com/qos-ch/logback/blob/v_1.2.11/logback-classic/src/main/java/ch/qos/logback/classic/spi/ThrowableProxy.java#L122. A mocked object is not a normal throwable and the implementation of Throwable.getSupressed() listed below will never return null like the mock did. public final synchronized Throwable[] getSuppressed() { if (suppressedExceptions == SUPPRESSED_SENTINEL || suppressedExceptions == null) return EMPTY_THROWABLE_ARRAY; else return suppressedExceptions.toArray(EMPTY_THROWABLE_ARRAY); }   Add Comment   This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)
