Do Not Use Java Thread.suspend () And Thread.resume () Methods 4040218

The Java Thread.suspend() method may cause Java application programs to hang. It is strongly recommended that you do not use the suspend() and resume() methods.

Hangs may occur because a thread holding a lock is suspended and the thread responsible for resuming this thread needs this lock. This is a general problem with threaded programming because of improper usage of these primitives, which leads to application deadlocks.

Workaround: Use other appropriate synchronization methods, such as wait() and notify().

Timestamp Constructor Accepts Two-Digit Date (4047499)

java.sql.Timestamp accepts a two-digit year but does not allow for years beyond 1999 (it interprets a two-digit date as 19xx). This problem does not occur when a four-digit year is specified.

The java.sql.Timestamp class extends the java.util.Date class where several methods have been deprecated. To ensure forward compatibility, use the java.text.SimpleDateFormat methods.
