I joined in an organisation before 6 months as Ruby on Rails (ROR) Developer. I have complete experience as ROR Developer and with mid level front end skills. This organisation is wholly a JAVA based organisation where they have a small part build in ROR. That ROR part does not have much work for me to do hence I am being put in the JAVA projects so that I don't sit idle in office.

Also the people here have very good fluency in English and they are here for 5 - 10 years. My previous organisations are where your work speak for you. Here you have to speak for you. As I look very soft and struggle to speak good English they have decided that I am an under performer and treat me that way.

They behave like that I don't even exist in the team. If I ask, then they will assign tasks. Otherwise they won't. During Planning meetings, They don't even plan tasks for me or try to keep me occupied with work.

I would like to inform that though I am not a native English speaker I have a decent spoken English. I can adopt to any programming language easily. The problem here is it is more customised that one cannot google and figure out if something went wrong.

How to handle such situations?

You cannot easily communicate and you're a junior in the technology they use. That makes it very easy for you to get sidelined, as you are. The first thing to do is fix the communication barrier; if you can't afford to get English lessons, you have to study on your own.

Then you need to become more proficient in Java so they start thinking of you more as a peer, rather than someone they have to make work for. Again, you have to study on your own here if they use a framework or technology you're not very good at.

But the point is, even if you become best Java developer in the team, it will still be hard for you if you can't communicate.

Finally, tell your boss / manager / team lead that you want to start contributing more. Tell them you're taking English lessons (if you are) and ask them for their help in getting up to speed. This means asking them what areas you can improve in, other than language and technology, and also to work with you in giving you tasks that help you prove yourself in the eyes of the team. And then do the same thing every 3 months or so to see how you're improving.

6 months isn't very long to break into a team if you're an outsider of some sort. Just work as professionally as you can, be friendly and helpful, don't get frustrated and you'll prove your worth eventually.

You mistake is to assume that a evaluation as an underperformer is a sign of disrespect, and relate it directly to specific weaknesses. An underperformer is defined by his output in a specific field, and to be an underperformer in one field is not the end of the world, and being categorized as such is not disrespectful, but can be a rational decision of a project.

As I look very soft and struggle to speak good English they have decided that I am an under performer and treat me that way.

That sounds like you believe that they judge you by personality traits and language skills alone, and not based on your output. I found nothing in your text which otherwise suggests this. Interpret it from their viewpoint:

Imaging you have a task, where you know that a Java novice could do it in 2h, including requiring help, and due to the language barrier potentially with a misunderstanding causing delay/bugs/errors. Imagine now that you could do the task in 0.5h-1h because you are experienced. What would you do if your task is to execute the project and not to train the colleagues. Would you, even if you get pressure from your boss.

During Planning meetings, They don't even plan tasks for me or try to keep me occupied with work.

It is not the task of the project to "keep you occupied". It is your task to become valuable enough for the project to assign tasks to you. Plan your language training, Java training, and be willing to sacrifice an considerable amount of personal time for it, and talk to you boss.

A thing to be careful with is that while it doesn't hurt to ask for help, you shouldn't expect them to do it. Afterall, they have other team members they can easily communicate with and get work done but they have to put extra work in to communicate with you. In my personal experience, people will not put the extra work in for you. If anything, expect remedial work in such a situation as you currently are.

However, did you write this question yourself? If so it appears you have good command in writing english and perhaps good understanding. Can you ask your boss or manager if it is possible to communicate work to you in email or ticketing systems? Perhaps write your boss an email explaining you have trouble with understanding spoken english but you can understand written english much better.
