glGetActiveUniformBlockiv not functioning for vector output

See original GitHub issue

Issue details

When querying vector information from UniformBlocks (i.e. GL_UNIFORM_BLOCK_ACTIVE_UNIFORM_INDICES) only the first item is ever written.

Reproduction steps/code

I don’t have time to create a reproduction rn, but my stacktrace looks something like this

My code:

                val indices = allocateIntBuffer(count) // direct byte buffer as an int buffer
                indices.rewind()
                gl.glGetActiveUniformBlockiv( // gl is typealiased to Gdx.gl30
                    programId,
                    i, // index of the ubo
                    GL30.GL_UNIFORM_BLOCK_ACTIVE_UNIFORM_INDICES,
                    indices
                )
Libgdx: Lwjgl3GL30.java:484

	@Override
	public void glGetActiveUniformBlockiv (int program, int uniformBlockIndex, int pname, IntBuffer params) {
		params.put(GL31.glGetActiveUniformBlocki(program, uniformBlockIndex, pname));
	}
Lwjgl: GL31C.java:584

    @NativeType("void")
    public static int glGetActiveUniformBlocki(@NativeType("GLuint") int program, @NativeType("GLuint") int uniformBlockIndex, @NativeType("GLenum") int pname) {
        MemoryStack stack = stackGet(); int stackPointer = stack.getPointer();
        try {
            IntBuffer params = stack.callocInt(1);
            nglGetActiveUniformBlockiv(program, uniformBlockIndex, pname, memAddress(params));
            return params.get(0);
        } finally {
            stack.setPointer(stackPointer);
        }
    }

I may provide a proper reproduction later on.
