Inconsistent Compiler Error

[Dennis Putnam]

I am developing my Java app using Eclipse on Windows and am getting error free compiles on this method:

public static String[] encryptor(String pw,String propKey, String propText) {	
	String[] ar=new String[2];
	Cipher pbeCipher;
	try {
		pbeCipher = Cipher.getInstance("PBEWithMD5AndDES");
		pbeCipher.init(Cipher.ENCRYPT_MODE,getSecretKey(pw),new PBEParameterSpec(
                    String.format("%1$-8s",Registration.getInstance().getMemberNumber()).getBytes(),20));
		ar[0]=new String(KeyGenerator.binaryToHex(pbeCipher.doFinal(propKey.getBytes())));
		ar[1]=new String(KeyGenerator.binaryToHex(pbeCipher.doFinal(propText.getBytes())));
	} catch (NoSuchAlgorithmException | NoSuchPaddingException | InvalidKeyException | InvalidAlgorithmParameterException |
                     IllegalBlockSizeException | BadPaddingException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
	return(ar);
}

However, when I compile on Linux, I get these compiler errors:

[javac] /var/www/html/Applets/KCBSEvents/src/KCBSEvents/Helpers.java:228: <identifier> expected
[javac] } catch (NoSuchAlgorithmException | NoSuchPaddingException |InvalidKeyException | InvalidAlgorithmParameterException | IllegalBlockSizeException | BadPaddingException e) {

[javac] } catch (NoSuchAlgorithmException | NoSuchPaddingException |InvalidKeyException | InvalidAlgorithmParameterException | IllegalBlockSizeException | BadPaddingException e) {
[javac] ^

It is possible I am missing a library on the Linux side but the errors seem to indicate something else is wrong. Can someone clarify if this can be caused by simply a missing library or is there really something wrong with the syntax that Windows doesn't seem to mind? TIA.

Looks like it is complaining about the multi-catch exception feature that was added with Java 7. Any chance that the Linux system is compiling with a version of Java prior to Java 7?

Thanks for the reply. I hadn't thought of that but yes, that is exactly what is happening.
