Issue while using 'javac' with different versions of java
I am facing an issue while compiling a java code
The code was earlier compiling with a lower version of jdk i.e. 1.4.1.02 but now when I am compiling the same code with any higher versions, like 1.4.2, it is throwing an error.

bash-2.03$ /export/home/jdk/1.4.1_02/bin/javac -d /export/home/classes classpath .:/export/home/jar/util.jar:/export/home/jar/util_sdk.jar:/export/home/thirdparty/xerces-j/2.6.2/xercesImpl.jar:/export/home/thirdparty/rsa-bsafe/crypto-j/3.5.2/cryptoc/jsafe.jar:/export/home/thirdparty/javamail/1.3.1/mail.jar:/export/home/thirdparty/rsa-bsafe/cert-j/2.1.2/certj/certjWithNative.jar
The java compilation throws no error.

But when we use a higher version of java, like 1.4.2.03
bash-2.03$ /export/home/jdk/1.4.2.03/bin/javac -d /export/home/classes classpath .:/export/home/jar/util.jar:/export/home/jar/util_sdk.jar:/export/home/thirdparty/xerces-j/2.6.2/xercesImpl.jar:/export/home/thirdparty/rsa-bsafe/crypto-j/3.5.2/cryptoc/jsafe.jar:/export/home/thirdparty/javamail/1.3.1/mail.jar:/export/home/thirdparty/rsa-bsafe/cert-j/2.1.2/certj/certjWithNative.jar
We get an error 劵
