Running Java code on AIX locks up!

Question

I am a newbie to AIX and UNIX. I am running a Java program that updates some records in a database, but the program "locks up". Even a simple HelloWorld Java program on AIX 4.3.3 that all it does is do a System.out.println("Hello World"); does the same thing. What I mean by "lock up" is that I execute the Java command on the $ command prompt and the cursor goes to the next line and doesn't do anything else! This doesn't happen all the time-other times, my programs run fine. The JRE is 1.3.1. Anybody out there with experience running Java on AIX know what is going on with this? Thanks.

Lot's of experience with the Java runtime on AIX. Can you type at the shell prompt ($):
java -version
What comes back? If nothing, tell root (sysadmin) to reinstall and get the license for the java runtime. Otherwise, do this:
$ cat <<EOF >T.java
public class T { public static void main(String[] argv) {
System.out.println("Hello World!");
EOF
$ javac T.java && java TThen post back what happens.
