Getting No such algorithm exception while using TLSV1.2 in java 1.4 - bouncycastle

Question

I am trying to hit a webservice which supports TLSv1.2. I am using Java 1.4. It does not support TLSv1.2.
Now someone told me that BC could solve my problem.
Though does it work with a SSLEngine as drop in replacement somehow?
Is this possible with BC?
What do I have to do to get a working SSLEngine (for use with TLSv1 in a
nonblocking io scenario) without such low restrictions on primesize for DH.
What I tried:
Security.addProvider(new BouncyCastleProvider());
This alone seems not to solve the problem.
So instead of
SSLContext.getInstance("TLSv1"); //which works alas only little DH keys.
I tried calling the following:
SSLContext.getInstance("TLSv1","BC");
SSLContext.getInstance("TLS","BC");
SSLContext.getInstance("TLSv1.2","BC");
SSLContext.getInstance("ssl","BC");
Though all of them throws NoSuchAlgorithmException.

I could solve this by using bctls lib, but unfortunatelly it doesn't seem to have a version for Java 1.4.
The only version that I could find in Bouncy Castle's website and in Mvn Repository is bctls-jdk15on-157 (for Java >= 1.5).
Anyway, if an upgrade of your Java version is possible, you just need to add this jar to your project and use the org.bouncycastle.jsse.provider.BouncyCastleJsseProvider class (I've used Java 1.7 for this test):
// add the JSSE provider
Security.addProvider(new BouncyCastleJsseProvider());
// tests
SSLContext.getInstance("TLSv1.1", BouncyCastleJsseProvider.PROVIDER_NAME);
SSLContext.getInstance("TLSv1.2", BouncyCastleJsseProvider.PROVIDER_NAME);
SSLContext.getInstance("TLSv1", BouncyCastleJsseProvider.PROVIDER_NAME);
All tests above run without error.
Checking all the SSL protocols supported:
SSLContext context = SSLContext.getInstance("TLSv1", BouncyCastleJsseProvider.PROVIDER_NAME);
System.out.println(Arrays.toString(context.getSupportedSSLParameters().getProtocols())); // [TLSv1.1, TLSv1, TLSv1.2]
The output is:
[TLSv1.1, TLSv1, TLSv1.2]
