If you happen to try to debug any Java JNI programs using gdb on GNU/Linux you will soon come across error messages. For example : $ gdb --args java MyJavaProgramUsingJNI cannot find user-level thread for LWP nnn: generic error warning: Cannot initialize thread debugging library: versions of libpthread and libthread_db do not match The reason for this is that the java program mucks around with LD_LIBRARY_PATH and that prevents gdb from running correctly. To overcome this, you have to run your Java program and place a pause in the Java code, such as reading a key, and then in another shell, run gdb to attach to the running Java process. You can then set your breakpoint on your JNI code and debug it. Here is an example : Compile your Java program: $ javac JNITest.java Generate the JNI header file: $ javah -jni JNITest.java Create and compile your C code library: $ cat jnilib.c #include "JNITest.h" JNIEXPORT jint JNICALL Java_JNITest_addValues( JNIEnv...

It seems that the font rendering engine has changed. It looks very good and apparently uses the native ClearType on Windows now instead of it's own rendering (which was excellent). The only bad thing for me, is that it looks blurred now. When running jedit or NetBeans with Windows Look and Feel, the font is the same as native apps but it's subtly different. They look as good as native Windows fonts, but on my LCD they look almost like Bold has been turned on. Windows apps font seem thin compared to the heavier Java rendered font.

Cay Horstmann's Blog: Java One Day 4 "The keynote ended with some big science: JMars and the use of Java at CERN. When Gosling visited a control room at CERN that was filled with monitors, he asked whether they had any Swing apps. Well, all of them were Swing apps. "
Unit testing is extremely useful. I'm working through this excellent guide : Pragmatic Programmer: Unit Testing in Java with junit I have yet to find any good websites for junit, but the book is great. I've had a lot of success in some small projects, using NetBeans 6.1 to generate empty tests for each class member. Then you go and fill them in. It's helping me to refresh my memory about the code and great to think of new ways to test the code and new ways to write the code.
I've found these so far, I'd like to find more. It's always so useful to read and follow an interesting thread on Java programming, you learn from the discussion and the examples given.

http://www.drjava.org/ Dr.Java is an interesting little IDE that helps newcomers develop Java code. Although aimed at newcomers, it seems to have lots of advanced features. It could be a useful alternative to the larger IDEs like Eclipse and NetBeans. I found it useful to create small projects and play around with compiling and easily interacting with Java code, without the hassle of creating a large project in a full featured IDE.

An old article from 2004, but another look at the Java 5.0 language features and comments about them. TheServerSide.com: JDK 5 in Practice by Cedric Beust
Bruce Eckel writes about Java possibly being a dead end? Java: Evolutionary Dead End I don't agree, but he makes some interesting observations about the recent complexity of Java since the changes made at 5.0. His comment : If Java is to be saved at all, it needs to become like C; a workhorse that you can rely upon. In fact, any future changes to the language need to be things that simplify and clarify the language and its use (say, fixing the classpath problem), and flesh out (for example) incomplete libraries that have languished (like JMF). It would be great to simplify, and flesh out the libraries but I don't believe Java is in any danger of dying. Another article : On Closures mentions that generics were a disaster as it made Java much harder to learn.
