Method Detail

warnHandle

public static void warnHandle(java.lang.Throwable ex,
                              java.lang.String note)

Log a warning message to the logger 'org.archive.util.DevUtils' made of the passed 'note' and a stack trace based off passed exception.

Parameters:

ex - Exception we print a stacktrace on.

note - Message to print ahead of the stacktrace.

extraInfo

public static java.lang.String extraInfo()

Returns:

Extra information gotten from current Thread. May not always be available in which case we return empty string.

betterPrintStack

@Deprecated
public static void betterPrintStack(java.lang.RuntimeException re)

Deprecated. This method was never used.

Nothing to see here, move along.

sigquitSelf

public static void sigquitSelf()

Send this JVM process a SIGQUIT; giving a thread dump and possibly a heap histogram (if using -XX:+PrintClassHistogram). Used to automatically dump info, for example when a serious error is encountered. Would use 'jmap'/'jstack', but have seen JVM lockups -- perhaps due to lost thread wake signals -- when using those against Sun 1.5.0+03 64bit JVM.
